Question

Determine the hybridization states of the carbon atoms in but-1-en-3-yne ($CH_2=CH-C\equiv CH$) from left to right.

Answer: A

💡 Solution & Explanation

Numbering starts from the double bond (priority). C1 and C2 are doubly bonded, thus $sp^2$ hybridized. C3 and C4 are triply bonded, thus $sp$ hybridized.
