Question

The bond angle between carbon and hydrogen atoms in a methane molecule is _____ degrees.

• A. 109.5

Answer 1

The correct option is A 109.5
The carbon atom in methane $\left({\text{CH}}_4\right)$ is ${\text{sp}}^3$ hybridised. The four hybrid orbitals in a methane molecule are oriented along the four corners of a tetrahedron, to minimise the repulsion.

Hence, the bond angle in methane is ${\text{109.5}}^0$.
