What to study in organic
chemistry?



General organic chemistry(Ref:Peter Sykes)
Electrophiles & Nucleophiles:
Which type of systems act as E+ or Nu-?
Same system act as E+ or Nu- depending on
which system it reacts.
Acidity and Basicity:
General idea of order of acidity and basicity.
Bronsted & Lewis theory.
Effect of back-bonding , aromaticity, SIR,etc.


Funda is conjugate acid or conjugate base as
the case may be if stable then that base or acid
is strong.
Solvent and its role in reaction mechanism.
Inductive effect,Hyperconjugation,Resonance.
Aromaticity.
Tautomerism(keto-enol)
Keto-Enol Ratio – Various factors like relief of
angle strain.
Solvent & Temp. Effect on Keto-Enol Ratio

H-Bonding:
Some cases for which gemdiol is stable.
Nu- of ions in protic and aprotic solvent.
Effect of H-Bond on acidity,basicity,B.P.
Order,H-Bonding during tautomerism.
