Match the reactions in Column $I$ with appropriate options in Column $II$.

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

Q: Match the reactions in Column $I$ with appropriate options in Column $II$. 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

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.
