Question

what orbitals are used to form each indicated bond in the molecule shown? part: 0 / 4 part 1 of 4 σ bond a c3 - c4

Explanation:

Step1: Determine hybridization of C3 and C4

C3 and C4 are involved in a double - bond. Carbon atoms in a double - bond are $sp^{2}$ hybridized.

Step2: Identify orbitals for bond a

The $\sigma$ bond between $sp^{2}$ hybridized C3 and $sp^{2}$ hybridized C4 is formed by the overlap of $sp^{2}$ orbitals.

Answer:

$sp^{2}-sp^{2}$
