According to vsepr theory, molecules adjust their shapes to keep which of the following as far apart as possible?
a. inner-shell electrons
b. the electrons closest to the nuclei
c. mobile electrons
d. pairs of valence electrons

d. pairs of valence electrons

Explanation:

Pair of valence electrons are kept as far apart as possible to avoid bond pair-bond pair repulsion. Each covalent bond is formed by the sharing of a pair of electrons. In its most stable 3D conformation a molecule will keeps its electron rich bonds far apart. For example, BeCl₂ has a linear structure where each of the Be-Cl bonds is 180° apart. Be has 2 valence electrons and can form a maximum of two covalent bonds.

it should be p1 v1 = p2 v2

i'm pretty sure it is letter c.) car
