Question

Number of hybrid orbitals present in a molecule of propene are:

• A. $12$
• B. $10$
• C. $9$
• D. $8$

Answer 1

Answer: (B)

$10$

In propene, two carbon atoms are $s{p}^2$ hybridized. One carbon atom is $s{p}^3$ hybridized. Overall, there are three orbitals each from $s{p}^2$ and four orbitals from $s{p}^3$ hybridization. Hence, a total of 10 hybrid orbitals in propene.
