Question

According to $VSEPR$ theory, the shape of $A{B}_3$ type of molecule in which the central atom has one lone pair of electrons:

• A. pyramidal
• B. tetrahedral
• C. trigonal planar
• D. linear

Answer 1

The correct option is A pyramidal

According to VSEPR theory, the shape of $A{B}_3$ type of molecule in which the central atom has one lone pair of electrons is pyramidal. An example of such molecule is $ammonia$ or $N{H}_3$. It has three bond pairs and one lone pair of electrons
