Question

the bond angle in ammonia is​

Answer 1

Answer:

Ammoniamolecule. Recall that the bond angle in the tetrahedral CH 4molecule is 109.5°. Again, the replacement of one of the bonded electron pairs with a lone pair compresses theangle slightly. The H-N-H angleis approximately 107°.

Answer 2

Answer:

AB3E: Ammonia, NH3

The ammonia molecule contains three single bonds and one lone pair on the central nitrogen atom (see Figure 8).

Lone pair electrons in ammonia.

The domain geometry for a molecule with four electron pairs is tetrahedral, as was seen with CH 4 . 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°. Again, the replacement of one of the bonded electron pairs with a lone pair compresses the angle slightly. The H-N-H angle is approximately 107°.
