Match Column I with Column II: Column I Column II (A) CH_3-CHBr-CD_3 on treatment with alc. KOH gives CH_2=CH-CD_3 as a major product. (P) E1 reaction (B) Ph-CHBr-CH_3 reacts fasterthan Ph-CHBr-CD_3. (Q) E2 reaction (C) Ph-CH_2-CH_2Br on treatment with C_2H_5OD\/C_2H_5O^{-} gives Ph-CD=CH_2 as the major product. (R) E1cb reaction (D) PhCH_2CH_2Br and PhCD_2CH_2Br react with same rate. (S) First-order reaction [JEE Adv 2006 P1]
