Q. Generally covalently bonded molecules:

1. have high boiling and melting point as compare to ionically bonded molecules
2. poor conductors of electricity
3. have weak intermolecular force

Which of the above is / are correct?
Answer: Only 2 and 3
Notes: Covalent compounds are formed by the sharing of electrons, hence the bonding is relatively weak. So, they have low melting and boiling points. On the other hand, ionic compounds are formed by the transferring of electrons and, thus, strong electrostatic forces holds the compound together. The strength in these forcesrequire a large amount of energy to break it apart hence boiling and melting points are high.
