Question

What is the number of moles of $sp^2$ hybrid carbon atoms in one mole of hexa-1,4-diyne?

• A. 5
• B. 3
• C. 4
• D. Zero

Hint:

Logic Tip: The suffix "-yne" indicates triple bonds ($sp$), "-ane" indicates single bonds ($sp^3$), and "-ene" indicates double bonds ($sp^2$). Since the name "hexa-1,4-diyne" only contains "yne" and implied alkane backbones, it fundamentally cannot contain any $sp^2$ carbons.

Answer 1

The Correct Option is D
