Answer to Question #204783 in General Chemistry for Rajay Myrie

Question

State the geometry of, and the bond angles in, the ammonia (NH3) molecule. 

Answer 1

In the ammonia molecule, one of the electron pairs is a lone pair rather than a bonding pair. The molecular geometry of NH 3 is called trigonal pyramidal (see Figure 9). Recall that the bond angle in the tetrahedral CH 4 molecule is 109.5°.
