Q. The ease of dehydrohalogenation with alcoholic $K O H$ in case of chloroethane (I), 2-chloropropane (II) and 2-chloro-2 methylpropane (III) is of the order

III $>$ II $>$ I

I $>$ II $>$ III

II > I > III

I $>$ III $>$ II

Rate of dehydrohalogenation

$3^{\circ} RX > 2^{\circ} RX > 1^{\circ} RX$

So $(III) > (II) > (I)$

III > II > I

I > II > III
