Q. 95.Q) CH3CH2CH2OCH3 and (CH3)2CHOCH3 are which of them and why? options 1)chain isomers 2) position isomers 3) ring chain isomers 4) funtional isomer

Q. how many structural isomer are possible when one of the hydrogen in compound given below is replaced by chlorine atom. diphenylmethyl is the compound: (1) 6 (2) 4 (3) 8 (4)7

Q.

The trichloromethyl group is meta directing when attached to benzene ring due to 1)hyperconjugation

2)reverse hyperconjugation

3) +I effect

4) -I effect
