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
