The carbon-carbon single bond in the following is formed by the overlap of which two orbitals?
$\mathrm{H}_{2} \mathrm{C}=\mathrm{CH}-\mathrm{C} \equiv \mathrm{N}$

Question

Quizplus · Accepted Answer

The carbon in the double bond ($=$) is $sp^2$ hybridized, and the carbon in the triple bond ($\equiv$) is $sp$ hybridized. Therefore, the carbon-carbon single bond between them is formed by the overlap of an $sp^2$ orbital from the double-bonded carbon and an $sp$ orbital from the triple-bonded carbon.
