3. this is a diagram of ammonia. this molecule has a central nitrogen atom singly bonded to three hydrogen atoms. the nitrogen atom also has one lone pair of electrons. the shape of this molecule can be classified as ________.a) linearb) trigonal planarc) tetrahedrald) trigonal pyramidal
Answer
Brief Explanations:
Molecular shape is determined by bonding pairs and lone pairs on the central atom. Ammonia ($NH_3$) has 3 bonding pairs and 1 lone pair on nitrogen. Lone pairs repel more strongly, distorting the tetrahedral electron geometry into a trigonal pyramidal molecular shape, which matches option D.
Answer:
D) trigonal pyramidal
