Answer 2

Answer: C. Trigonal planar

Explanation: VSEPR Theory : It predicts the geometry of the molecule from the number of electron pairs that surround the central atom.

Formula used :

Number of electron pairs =
`(1)/(2)[V+N-C+A]`

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms

C = charge of cation

A = charge of anion

In the given molecule, C is the central atom and H are monovalent atoms.

Number of electron pairs =
`(1)/(2)[4+2-0+0]=3`

The number of electron pairs is 3 that means the hybridization will be [texsp^2[/tex] and the molecular geometry will be trigonal planar.
