In the 1-bromo-1-methylcyclohexane, all b -hydrogen atom are equivalent. Thus, dehydrohalogenation of this compound gives only one alkene as follows:
(ii) CH3CHCH2CH3
(iii) CH3CH2CH2CH2Br
(iv) (CH3)3 C—Cl
Which 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.
