When 2,2-dibromobutane is heated at 200°C in the presence of molten KOH, what is the major organic product?

Question

Quizplus · Accepted Answer

When 2,2-dibromobutane is heated with strong base, it undergoes an elimination reaction to form an alkyne. The alkyne formed will have the same number of carbons as the starting material, but with two fewer hydrogens. Since 2,2-dibromobutane is a symmetric molecule, it will form a symmetric alkyne. The major product will therefore be but-2-yne, or answer choice D.
