Answer #1

molecular compounds ---> compound bonded with only COVALENT bodnings and no IONIC bonding

NOTE:

all those are MOLECULAR, since there are no IONIC bondings,

analysis

A). CH4 --> C-H is bonded covalently, and it is nonpolar

B). SO3 --> S and all other Oxygens share electrons around; therefore molecular

C). CH3COOH --> this is pretty similar to CH4, this is organic chemistry, all carbon-oxygen-hydrogen are covalent

D). O2 --> this is nonpolar covalent, since oxygen share its electron with the other oxygen

E). HF --> this may be tricky, since H is in the left side of the table and F in the right one, but H will form a molecular compound

note that molecular is pretty similar to covalent(polar or nonpolar)
