ðŸ¤“ Based on our data, we think this question is relevant for Professor Dunning's class at TEXAS.

The bond angle in NH_{3} is (smaller, larger) than the bond angle in CH_{4 }because

1. smaller; nitrogen is smaller than carbon.

2. larger; the bond angles in trigonal planar molecules are larger than those in tetrahedral molecules.

3. smaller; the hybridization of nitrogen results in smaller bond angles than the hybridization of carbon.

4. smaller; the bond angles in trigonal planar molecules are smaller than those in tetrahedral molecules.

5. smaller; the unshared pair of electrons on nitrogen is more repulsive to the bonded electron pairs.

6. larger; the hybridization of nitrogen results in larger bond angles than the hybridization of carbon.

7. larger; nitrogen is larger than carbon.
