The observed bond angles in ammonia are 107°. Which of the following statements is least consistent with this observation?
a. ) The repulsion between lone pair (lp) and bond pair (bp) orbitals is greater than that between bp and bp orbitals.
b. ) The valence-bond model suggests that the sigma-bonds involve unhybridized p-orbitals of nitrogen.
c. ) The VSEPR method suggests an approximately tetrahedral electron group geometry.
d. ) The lp and bp orbitals on nitrogen are sp3 hybrids.
e. ) The N-H bonds are all equivalent to each other.
I know the (c) is false.
