Column $I$ Column $II$
$(A)$ $Image$ $(p)$ Racemic mixture
$(B)$ $Image$ $(q)$ Addition reaction
$(C)$ $Image$ $(r)$ Substitution reaction
$(D)$ $Image$ $(s)$ Coupling reaction
  $(t)$ Carbocation intermediate

  • A
    $(A-r, p, t) ;(B-t) ;(C-p, t) ;(D-s)$
  • B
    $(A-q, s, t) ;(B-p) ;(C-p, r) ;(D-p)$
  • ✓
    $(A-r, s, t) ;(B-t) ;(C-p, q) ;(D-r)$
  • D
    $(A-p, q, r) ;(B-t) ;(C-s, t) ;(D-q)$
✓

Answer

Correct option: C.
$(A-r, s, t) ;(B-t) ;(C-p, q) ;(D-r)$
c
$(A)$ It is an example of electrophilic substitution reaction which results in coupled product hence it is coupling reaction also.

$(B)$ Pinacole-pinacolone rearrangement. In this reaction intermediate is carbocation.

$(C)$ It is an example of addition reaction by carbonyl compounds and both enantiomers will be formed. Hence, racemic mixture will be obtained. $Image$

$(D)$ It is an example of nucleophilic substitution.
