well iit jee has no fixed pattern, anything can be asked ! but you must do all the reactions given in jee syllabus for organic chemistry thoroughly with their mechanisms !! some of which includes :-

1 Wurtz reaction and decarboxylation reactions.

2 Electrophilic substitution reactions(benzene): halogenation, nitration, sulphonation, Friedel-Crafts alkylation and acylation

3  Reimer-Tieman reaction, Kolbe reaction.

4 Grignard reactions

5 esterification

6 Williamson’s  Synthesis

7 aldehydes and ketones : oxime and hydrazone formation; aldol condensation, Perkin reaction; Cannizzaro reaction; haloform reaction and nucleophilic addition reactions (Grignard addition)

8 stefans reaction

9 Sandmeyer and related reactions of diazonium salts

* this is not the complete list. i have given only those which are highlighted in jee syllabus and hence are important.

atleast what should i study in org. chemistry so that i could get good marks in this sub.coz i don''t lyk org chemistry sugest me the min syllabus
