Arrangement of (CH3)3C –,(CH3)2CH –,CH3CH– when attached to benzyl or an unsaturated group in increasing order of inductive effect is
(a) (CH3)3C – < (CH3)2CH – < CH3CH2
(b) CH3CH– < (CH3)2CH – < (CH3)3C –
(c) (CH3)2CH – < (CH3)3C – < CH3CH
(d) (CH3 )3C – < CH3CH < (CH3)2CH –.

(b) : –CH3 group has +I effect, as number of – CH3 group increases the inductive effect increases.
