Answer 2

Name of Compound is Homologous Series

Explanation:

• (a) Ethane and Propane Comes after Methane in the Higher Homologous Series

Ethane - $C_2H_6$

Propane - $C_3H_8$

* Refer pic attached for reference to structure

• (c) The Organic Compound series which shows similar properties in the coming successive members (-$CH_2$ group)  is called Homologous Series.

Alkanes: $C_3H_8; C_4H_1_0$

Alkenes: $C_5H_1_0; C_8H_1_6$

Alkynes: $C_7H_1_2$
