2. In measurements of the structure of molecules, some interesting trends are observed. The bond angle (H-C-H) in CH4 is 109°, as we would expect for a molecule in the tetrahedral VSEPR class. However, other molecules in the same VSEPR class, such as ammonia (NH3, H-N-H= 107°) and water (H2O, H-O-H = 105°), have smaller bond angles than expected. Explain the basis for the bond angle trend: CH4 > NH3 > H2O.
