Two non-metal combine with each other by the sharing of electron to form a compound X.(a) What type of chemical bond is present in X?
(b) State whether X will have high melting point or low melting point?
(c) Will it be a good conductor of electricity or not?
(d) Will it dissolve in an organic substance or not?
(a) Covalent bond is present in compound X as it is formed by the sharing of electrons.
(b) Compound X will have a low melting point because it is a covalent compound.
(c) Being a covalent compound, it is not a good conductor of electricity.
(d) Yes, being a covalent compound it will dissolve in an organic substance.
