Question

According to the VSEPR theory, what is the shape of a molecule that has a central atom bound to three other atoms with no lone pairs of electrons?

A. tetrahedral
B. bent
C. linear
D. trigonal bipyramidal
E. trigonal planar

Answer 1

E.) The shape of molecule which can form 3 bonds and no lone pair of electrons on central atom is trigonal planar.

Answer 2

Answer: E. trigonal planar

Explanation:

According to VSEPR theory:

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

where, V = number of valence electrons present in central atom i.e. carbon = 4

N = number of monovalent atoms bonded to central atom=3

C = charge of cation = 0

A = charge of anion = -1

If a central atom is bound to three other atoms with no lone pairs of electrons,the number of electrons is 3 that means the hybridization will be
`sp^2` and the electronic geometry of the molecule will be trigonal planar as the electron pairs will repel each other and attain a position which is most stable.
