Question 5 • Chemistry

The shape of a molecule is trigonal planar. How many electron domains around the central atom does this molecule most likely have?

Answer
A
zero
B
two
C
three
D
four

Explanation

In VSEPR theory, a trigonal planar shape forms when the central atom has three electron domains arranged in a plane. These domains repel one another and spread out evenly, producing bond angles of about 120°. Therefore, the correct choice is three.
