Hi all…

You must be wondering how can I even think of learning chemistry and that too organic chemistry in just two minutes..Right??

But to be honest, after you spend 5 minutes reading my article, you will genuinely be able to revise your complete organic chemistry for JEE as well as AIPMT in just 2 minutes..

So let’s start with the journey which is destined to be ending with the words, “Yaaaa…This was worth..Organic is widespread but not that bad also.”

See, like a normal tutor I won’t be asking you to start writing with a pen and something..I am just going to take you to the world of resplendent rainbows..

So let’s just picture a rainbow..

You know it is made up of seven colors..

The so called “VIBGYOR” you would have learnt since your grade 7 or so.



This violet color should remind you of the basics of organic chemistry.

Now, what we can have in the basics of organic chemistry is the different types of intermediates, so now you need to concentrate on the three types of intermediates.

These are Carbocations, Carboanions, and Free radical intermediates.

To remember the stability of intermediates, you just need to keep in mind the different types of these intermediates. See among the carbocations, you can have a primary, secondary and tertiary intermediate. So whether it is a carbocation or a carboanion or a free radical, the intermediates can be stabilized according to the following effects.

They may be defined as

  1. Inductive effect.
  2. Resonance effect.
  3. Hyper conjugative effect.

Since I am very sure you all will be having the basic idea of these above mentioned effects.

Also you can keep one point in mind.

“The more stable the intermediate, the more fast or favorable will be the reaction.”

Also you should keep note for one more fact:

As soon as an intermediate is formed, it always tries to undergo rearrangement on its own, and then only any other reaction or further reaction steps should be taken in account.

Also as per my knowledge, I don’t think it is difficult for you to accept:

Whenever you find yourself in any dispute with your friends, you first try to solve it among yourselves, rather than taking help from any other person outside your friend circle. Right???

In a very similar way, whenever you are making a chemical reaction to occur, there will always be the intra molecular reaction which is going to be preferred over the intermolecular reaction.

Okkkkk, so the violet color of rainbow should be indicative of these basic chemistry facts from the chapter, “General Organic Chemistry” which you need to keep in mind while doing any organic question.

Moving on from Violet color to Indigo color, we will be coming across the Indigo color.


This color should be reminding you of another very important part of Organic Chemistry, i.e., Aromatic Hydrocarbons.

In this chapter you need to keep in mind these following topics.

Electrophillic aromatic substitution reactions and Nucleophillic aromatic substitution reactions.

There are five reactions of benzene which can be categorized as Electrophillic Aromatic substitution. These are:

1. Halogenations of benzene and its derivatives

2. Sulphonation of benzene and its derivatives

3. Nitration of benzene and its derivatives

4. Fridel Craft Alkylation of benzene and its derivatives

5. Fridel Craft Acylation of benzene and its derivatives

These five reactions which have been described above are kind of the most important reactions which should always be there at the back of your mind as soon as you encounter any reaction of aromatic system.

Finally coming over to the second type of reactions.

These are Nucleophillic Aromatic Substitution reactions that can be carried out in two different ways:

1. First is you need to take into account the benzyne mechanism where you need to have a very good base which can favor the abstraction of proton and thus the reaction is said to be going through by Elimination-Addition method.

2. The second type of reactions ARE the reactions undergoing Addition Elimination mechanism.

For these reactions, you need to have a good electron withdrawing group at the para position wrt the leaving group.

Sooooo, finally we are done with the Indigo color of rainbow. Now we are in a good position to take a flight for the Blue color.


This color should be reminding you of the derivatives of very simple alkanes which in this can be Alkyl and Aryl Halides.

Don’t worry I am not going to ask you to remember a lot of concepts in this chapter. Just you have to remember are a few important name reactions from the chapter.

The name reactions which you need to keep in mind are:

See, students are many times complaining, “It’s very difficult to solve organic questions. Moreover, those conversion questions are damn too difficult.”

I think many of you who are reading also might be feeling the same. So, one very important point to be noted over here is how and in what order you should be doing the chapters of class 12 Organic Chemistry.

So from the topic alkyl and aryl halide, you need to remember the name reactions like:

1. Sandmayer’s reaction

2. Markovnikoff and Anti-Markovnikoff reaction

3. Finkelistein reaction

Now coming to the green color, you need to come over to the topic, Alcohols, Phenols and Ethers.

Green:Here in this topic also, you need to concentrate on the nucleophillic substitution reactions and you can thus concentrate on these name reactions:

  1. Williamson’s synthesis
  2. Reaction with Baeyer’s reagent
  3. Reimer-Tiemann reaction
  4. Kolbe’s reaction
  5. Victor Meyer reaction

Finally you can come over to another shade that is Yellow.

Yellow must be reminding you of another important chapter of organic chemistry which comes to the carbonyl compounds.

Here in this chapter you need to remember another important chemistry concept.

You just have to imagine a small baby sleeping in bed. If you go and disturb the baby, it starts crying right. So to make it sleep again you just need to divert its mind in other direction.

So is the case with carbonyl compounds. The carbonyl compounds are just like these small babies. As and when some nucleophile goes and disturbs the carbonyl compound, it gets irritated. Once the carbonyl compound is disturbed by the nucleophile, it either gets stabilized by nucleophillic addition reactions  or it undergoes nucleophillic  substitution reactions. Thus you need to remember all the nucleophillic addition or substitution reactions.

So now coming over to Orange color

This color should be reminding you of the chapter “Carboxylic acid and its derivatives”

Here again you need to remember certain important name reactions which are going to help you out in almost all the conversion questions.

These are:

  1. Etard reaction
  2. Stephen reaction
  3. Rosenmund reduction
  4. Gattermann Koch reaction
  5. Oppenauer oxidation reactions
  6. Haloform reaction

Finally coming to the red and the most beautiful color is for the chapter amines and their derivatives.

This chapter is important since it is not like the other carbonyl and its derivatives reactions.

Here you have to focus on the behavior of amines and its compounds as the nucleophillic reagents which are going to attack the carbonyl centers.

So readers, I have here tried to compile all the organic chapters in a very short and easy to handle way.

I am sure if you go through the important points which I have tried to write up here you are going to enjoy the upcoming questions of Organic Chemistry.

So I wish you all the best for your organic practice and hope you feel happy and satisfied with the answers..
