(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.

Answer 1

(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).
