@ chandrasekhar solomons are better as it explains each and every concept more precisely , specially the mechanism , u can use that for mechanism . but ranjeet shahi explains the concept in shrtcut...
@ chandrasekhar yes , solomons will cover all the concepts that are there in it , but thats for advanced , i mean the problems and mechanism the way they explained are of advanced level . u can...
@ shinaz in a group while coming down from top to bottom , due to increase in size and involvement of d and f orbital , the outermost ns2 electron are not shielded or have ineffective sheilding by d...

From Hiesenberg’s Uncertainity princple, p*x > = h/4pi (40/1000)*45*x = h/4pi. put h and pi value and get x. that would be the error/uncertainity in position x .i.e. wavelength.
@ ritesh i am giving the approach to solve this question . if u can recall the gas law , m1v1 = m2v2, that have to be applied here directly as everything is given . m1 is the initial molarity which...
the common name of the compound H2C-CHO is “vinyl chlirode”. ALL THE BEST for your future ….….….….….….….….….….….….….….….…..
Radium has atomic number 88. it is a 2 nd Group element (Alkali earth metal) and 7 th period element. It’s oxidation number is 2.
@ manish i am giving some tips on how to remember such things 1- frst of all make a list of organic name reaction that are there in you book , u can take the help of sudy material as well 2- for...
Charels law states that at constant pressure the volume of gas directly proportional to its temparature.
The first organic compound prepared in labaratory is UREA(Sodium accitate). It was prepared by Wholer.
Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
Glass is also called as supercooled liquid.Because it do not form a crystalline structure, but instead forms an amorphous solid that allows molecules in the material to continue to move.
S-Block elements is Lithium , Sodiam , Potassium , Rubedium , Caesiumc, Francium. ….….….….….….….….….….….….….….….….….
From the principle of DIrective influence if ther is more than two groups on benzene and if both shows -M or -I effect then the elctrophile would attack near more -M effect shoeing group. Therefore,...
CCl 4 is an electrophile because chlorine has vacant d orbitals. And thus are attracted to an electron rich centre. Most electrophiles other than ccl4 has posotive charge over them. and has tenddency ...
Dear sunandaverma, There is no reason for why and whynots in IUPAC nomenclature. U will have to go through that and remmebr how to write their names.
1,3-pentadiene 1,4-pentadiene 2-Methyl-1,3-butadiene(aka isoprene) 3-Methylbutene-2 3-Methylbutene-1 Pentene-1 Pentene-2 these are the divisions based on structures.
Yes, it is correct. This is the part of an excpetion. .i.e. there is no proper explanation but consider it as exception and remeber it.
H2S2O3 is the mixed anhydride of H2SO4 and H2S. 2 H 2 S 2 O 3 ⇔ 2 H 2 S O 3 + S 2 . H2S2O3 dissociates into H2SO3 and S2 on heating thus.
-OCOR is know as Ester Group. and -COR is ketone group. and if also -COR has one H attached then it would be known as Aldehyde.
The simple reason is: Carbon being vaery small and has valency 4 that means it neither gains electrons nor loose them. It has the tendency to share the elctrons with other atoms. Therfore it makes...
1/k = R*1^2*(1/2^2 – 1/5^2) 1/k = R(1/4 – 1/25) = 21R/100 K = 100/21R f = c/k = 100c/21R where k is wavelength and c is speed of light
