compounds?
a. Covalent molecular compounds share their electrons forming polar and
nonpolar bonds
b. They contain carbon and hydrogen atoms that react readily with oxygen
gas
c. Because they generally have low melting and boiling points and the
addition of a small amount of energy causes intermolecular attraction to
break
d. Molecules easily reactwith heat-producing flames​
