Homework Help: Chemistry

Posted by Dani on Tuesday, September 17, 2013 at 9:09pm.

Although the VSEPR theory is correct in predicting that CH4 is tetrahedral, NH3 is trigonal pyramidal,
and H2O is bent, the HNH angle in NH3 is only 107.3 and the HOH angle in H2O is only 104.5.
Explain these deviations from the expected tetrahedral angle of 109.5.

I think it has something to do with the electron repulsion but I'm not exactly sure. I remember my professor talking about a cube.
