Question

Pls help ASAP on both.

Why do you need three equivalents of base in the synthesis of a terminal alkyne
from a suitable dihalide?
This is incorrect, only two equivalents of base are required
Jy
Without the third equivalent of base the mechanism would be SN1 and not an
elimination
The full reaction would not go to completion otherwise
All dihalides always require excess base for the synthesis of all alkynes
Terminal alkynes cannot be synthesized from dihalides
