Question

Look at the image shown

:F
What does this image represent?
Linear molecule with one domain
Linear molecule with two domains
Tetrahedral molecule with four domains
Trigonal planar molecule with three domains

Answer 1

Step-by-step explanation:

It is known that an electron pair represents a domain. Hybridization of
`BF_(3)` will be calculated as follows.

Hybridization =
`(1)/(2)[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]`

Valence electrons of boron are 3 and no. of bonded atoms in a
`BF_(3)` molecule is 3.

Therefore, calculate hybridization of
`BF_(3)` as follows.

Hybridization =
`(1)/(2)[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]`

=
`(1)/(2)[3 + 3 + 0]`

= 3

Hence, hybridization of
`BF_(3)` is
`sp^(2)`, that is, trigonal planar.

Thus, we can conclude that the given image represents that it is a trigonal planar molecule with three domains.
