For each of the four molecules below, complete the following:

a$.$ Draw in the pair of electrons shared between atoms. Draw the electrons closest

to more electronegative atoms or in the middle of the bond if the atoms are

equally electronegative.

b$.$ For each ATOM, determine if it has any electrons that are shared unequally, if so$,$

write a partial charge $(+$ or $-)$ next to that atom.

c$.$ Label all POLAR bonds.

d$.$ Label each of the molecules below as polar or nonpolar.

Please make sketch as said in the questions.$|$
