Question

What is the bond angle of a methane molecule that contains four hydrogen atoms bonded to one carbon atom?

Answer 1

Tetrahedral molecules have bond angles of 109.5 degrees

Answer 2

Answer: The bond angle in methane compound is 109.5°

Step-by-step explanation:

The chemical formula of methane molecule is
`CH_4`

The equation used to calculate hybridization follows:

`\text{Number of electron pair}=(1)/(2)[V+N-C+A]`

where,

V = number of valence electrons present in central atom

, carbon = 4

N = number of monovalent atoms bonded to central atom = 4

C = charge of cation

A = charge of anion

Putting values in above equation, we get:

`\text{Number of electron pair}=([4+4])/(2)=4`

The number of electron pair are coming out to be 4. This means that the hybridization will be
`sp^3` and the electronic geometry of the molecule will be tetrahederal.

The bond angle between the atoms when the electronic geometry is tetrahederal is 109.5°

The image of the methane molecule is attached below.

Hence, the bond angle in methane compound is 109.5°
