JEE MAIN - Chemistry (2002 - No. 13)
Arrangement of (CH3)3C-, (CH3)2CH-, CH3-CH2- when attached to benzyl or an unsaturated group in increasing order of inductive effect is
(CH3)3C- < (CH3)2CH- < CH3-CH2
CH3-CH2- < (CH3)2CH- < (CH3)3C-
(CH3)2CH- < (CH3)3C- < CH3-CH2
(CH3)3C- < CH3-CH2- < CH3)2CH-
Explanation
$$ - C{H_3}$$ group has $$+I$$ effect, as number of $$ - C{H_3}$$ group increases, the inductive effect increases.
Therefore the correct order is
$$C{H_3} - C{H_2} - < {\left( {C{H_3}} \right)_2}CH - < {\left( {C{H_3}} \right)_3}C - $$
Therefore the correct order is
$$C{H_3} - C{H_2} - < {\left( {C{H_3}} \right)_2}CH - < {\left( {C{H_3}} \right)_3}C - $$
