Chemistry - Hydrocarbon Question with Solution | TestHub

Question Explanation: Asking about the correct match between reactions of alkynes and reagents. Concept : This question is based on

(a) Birch reduction

(b) Rosenmund reduction

(c) Isomerisation of alkynes

Solution:

${\mathrm{CH}}_3-{\mathrm{CH}}_3-\mathrm{C}\equiv \mathrm{CH}\underset{\Delta }{\overset{{\mathrm{NaNH}}_2,\Delta }{\to }}{\mathrm{CH}}_3-\mathrm{C}\equiv \mathrm{C}-{\mathrm{CH}}_3$ (2-butyne)
