Question

The outer orbitals of $C$ in ethene molecule can be considered to be hybridized to give three equivalent $s p^{2}$ orbitals. The total number of sigma $(\sigma)$ and pi $(\pi)$ bonds in ethene molecule is

• A. 3 sigma $\left(\right.\sigma \left.\right)$ and 2 pi $\left(\right.\pi \left.\right)$ bonds
• B. 4 sigma $\left(\right.\sigma \left.\right)$ and 1 pi $\left(\right.\pi \left.\right)$ bonds
• C. 5 sigma $\left(\right.\sigma \left.\right)$ and 1 pi $\left(\right.\pi \left.\right)$ bonds
• D. 1 sigma $\left(\right.\sigma \left.\right)$ and 2 pi $\left(\right.\pi \left.\right)$ bonds
