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 =[tex]\frac{1}{2}[V+N-C+A][/tex]
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 =[tex]\frac{1}{2}[4+2-0+0]=3[/tex]
The number of electron pairs is 3 that means the hybridization will be [texsp^2[/tex] and the molecular geometry will be trigonal planar.
