Account for the following statements:
(i) Ethene is a covalent compound.
(ii) Carbon atoms from a strong bond.
(iii) Carbon shows catenation property.
(iv) Pentane has higher boiling point than methane.
(v) Alkenes have double bonds.

Explanation

(i).
(ii). (iii). (iv). Boiling point temperature pentane (309K) is higher than that of methane because its molecular size is more. As a result, inter-molecular forces of attraction in pentane are more than in ethane.
(v).
