	Column-I		Column-II
(P)		(1)	Elimination
(Q)		(2)	Rearrangement
®		(3)	Carbocation intermediate
(S)		(4)	Hoffmann product

\( \longrightarrow \)
CH3CHz — CHCHs F CH3sCHz— CH=—CH:
H CHs CH;— C—C—CHs CHs OH
CHs HaC— C—CHzCl

• A. P(1, 2, 3, 5); Q(1, 4); R(1, 2, 3, 5); S(1, 2, 3)
• B. P(1, 3, 4); Q(1, 2, 3); R(4, 5); S(4)
• C. P(1, 3, 4); Q(2, 4, 5); R(1, 4, 5); S(3, 4, 5)
• D. P(2, 3); Q(1, 2, 3); R(4,5 ); S(4)

Answer 1

The correct option is A P(1, 2, 3, 5); Q(1, 4); R(1, 2, 3, 5); S(1, 2, 3)

(P) Dehydration (elimination of $H_{2}O$) proceeds through carbocationic intermediate which will undergo rearrangement.
(Q) Elimination of $HF$ from fluoroalkanes yields Hoffmann product
(R) Same as (1)
(S) Elimination of $HCl$ proceeds through carbocation intermediate.
