Current Question (ID: 10817)

Question:

$\text{The number of } \sigma \text{ and } \pi \text{ bonds in the molecule CH}_2\text{Cl}_2 \text{ are -}$

Options:

1. $2 = (\sigma_{C-Cl}), 1 = (\sigma_{C-H}), \text{ and } 1 = \pi$
2. $2 = (\sigma_{C-Cl}), 2 = (\sigma_{C-H}), \text{ and } 0 = \pi$ (Correct)
3. $2 = (\sigma_{C-Cl}), 1 = (\sigma_{C-H}), \text{ and } 1 = \pi$
4. $2 = (\sigma_{C-Cl}), 1 = (\sigma_{C-H}), \text{ and } 1 = \pi$

Solution:

$\text{Hint: A single bond is a sigma bond while a multiple bond is composed of one sigma bond together with pi or other bonds. A double bond has one sigma plus one pi bond, and a triple bond has one sigma plus two pi bonds}$ $\text{Explanation:}$ $\text{Step 1: Below is the structure of dichloromethane}$ $\text{CH}_2\text{Cl}_2$ $\text{Step 2: Count the sigma, and Pi bond in the above dichloromethane compound structure}$ $\text{There two C-H sigma (}\sigma_{C-C}\text{) bonds and two C-Cl sigma (}\sigma_{C-H}\text{) bonds in the given compound.}$ $\text{Since dichloromethane contains only single bonds, there are no pi bonds present. The molecule has 4 sigma bonds total: 2 C-H bonds and 2 C-Cl bonds, and 0 pi bonds.}$
