In an SN2 substitution reaction of the type which one of the followings has the highest relative rate?
CH3-CH2-CH2Br
CH3-CH(CH2)-CH2Br
CH3C(CH3)2CH2Br
CH3CH2Br
B.
The mechanism of electrophilic addition reaction is consistent with the occurrence of rearrangement leading to more stable carbocation.
The order of stability of carbocation is as;
T > S> P > CH3
Consider the following compounds:
The correct decreasing order of their reactivity towards hydrolysis is;
(ii) >(iv) > (iii) > (i)
(i) > (ii) > (iii) > (iv)
(iv) > (ii) > (i) > (iii)
(iv) > (ii) > (i) > (iii)
