Question

internal alkyne from 3-Hexanone​

Answer 1

Answer:

There are two alkynes, 2-hexyne and 3-hexyne, which can give 3-hexanone. ... However, internal (nonterminal) alkynes can give mixtures of two products since the sp carbons of all internal alkynes can only be bonded to one other carbon. In essence, Markovnikov's Rule only works for terminal alkynes...
