TestHub · Accepted Answer

The initial compound is magnesium carbide M g 2 ​ C 3 ​ , not a Grignard reagent. Hydrolysis Mg₂C₃ + 4H₂O → CH₃C≡CH + 2Mg(OH)₂ gives propyne K; HgS O 4 ​ /dilute H 2 ​ S O 4 ​ hydration gives acetone L; LiAl H 4 ​ gives isopropanol M; dehydration gives propene N. K/M differ in iodoform, bromine water and silver-acetylide tests (1,3,5). M/N differ in iodoform and bromine water (1,3). K/L differ in all five tests. L/N differ in iodoform, bisulphite, bromine water and DNP, not ammoniacal AgN O 3 ​ . Correct matching option: D.
