Show Answer
Solution:
- (d) $Br_2$ in $CCl_4$ (a), $Br_2$ in $CH_3 COOH$ (b) and alk. $KMnO_4$ (c) will react with all unsaturated compounds, i.e., 1, 3 and 4 while ammoniacal $AgNO_3$ (d) reacts only with terminal alkynes, i.e., 3 and hence compound 3 can be distinguished from 1, 2 and 4 by. ammoniacal $AgNO_3(d)$.
