Short Answer TypeWhich compound in each of the following pairs will react faster in SN2 reaction with HO–?
(a) CH3—Br or CH3I
(b) (CH3)3 Cl or CH3Cl2
(c) CH2=CHBr or CH2 = CH—CH2Br.
(a) CH3I (Due to its bigger size thus better leaving group.
(b) CH3Cl (As the size of the alkyl group increases the reactivity decreases and CH3Cl have less number of alkyl group.
(c) CH2 = CHBr (Due to lesser number of alkyl group).
(ii) CH3CHCH2CH3
(iii) CH3CH2CH2CH2Br
(iv) (CH3)3 C—Cl
