1.	Which of the following reagents would convert but-1-yne into but-2-yne?A. ammoniacal `CuCl`B. `(NaNH_2)/(NH_3(1))`C. ammoniacal `AgNO_3`D. Ethanolic `KOH`, heat
Answer» Correct Answer - D Acetylene homologues isomerize when heated with ethanolic KOH, the tripe bond moving towards the centre of the chain: `CH_3CH_2C-=CHunderset(KOH)overset("Ehanolic")to[CH_3CH=C=CH_2]toCH_3C-=CCH_3`
