# Problem: The bond angle in NH3 is (smaller, larger) than the bond angle in CH4 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.

The bond angle in NH3 is (smaller, larger) than the bond angle in CH4 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.
