Grade 11 Chemistry question I need help with Please!!!?

Stronger bonds are solid and insoluble, and bond strength in order is non-polar covalent, polar covalent, and ionic. 1 is probably non-polar covalent because it is a liquid at room temperature and doesn't require extreme temperatures for boiling/melting points. 2 may be polar covalent because of its solubility, and 3 is most likely ionic.
