उत्तर
(a) Covalent bond is present compound X because it is formed by sharing of electrons.
(b) Compound X has a low melting point because it is a covalent compound.
(c) Being a covalent compound, it will not be a good conductor of electricity.
(d) Covalent compounds dissolve in an organic solvent. Since X is a covalent compound, it will dissolve in an organic solvent.
