Answer to Question #84037 in Physical Chemistry for Richie Ocranson

Question

.Assess the effect of bonding and non-bonding electron repulsion on the shape of molecules with references of water , ammonia and methane,

Answer 1

Solution:

In the NH3 molecule, there is one sp3 - a hybrid orbital filled with a pair of electrons, and it pushes the other three orbitals of the N - H bond away from it, reducing the angle to 107 °. In the H2O molecule - two orbitals with pairs of electrons. Their influence on the communication orbitals is even stronger, and the H-O-H angle decreases to 104.5 °.
