Question

Given below are certain matching type questions, where two columns (each having 4 items) are given. Immediately after the columns the matching grid is given, where each item of Column I has to be matched with the items of Column II, by encircling the correct match(es). Note that an item of Column I can match with more than one item of Column II. All the items of Column II must be matched. Match the following :
Column I
(A) C₆H₅CH₂CD₂Br on reaction with C₂H₅O– gives C₆H₅–CH=CD₂
(B) PhCHBrCH₃ and PhCHBrCD₃, both react with the same rate
(C) C₆H₅CH₂CH₂Br on treatment with C₂H₅O– and C₂H₅OD gives C₆H₅CD=CH₂
(D) C₆H₅CH₂CH₂Br reacts faster than C₆H₅CD₂CH₂Br on reaction with C₂H₅O– in ethanol
Column II
(p) E1 reaction
(q) E2 reaction
(r) E1cB reaction
(s) First order reaction
