Solution
| Sr. No. | Members | Structural formula |
| 1. | Methane | \[\begin{array}{cc} \ce{H}\\ |\\ \ce{H - C - H}\\ |\\ \ce{H}\\ \end{array}\] |
| 2. | Ethane | \[\begin{array}{cc} \ce{H}\phantom{...}\ce{H}\\ |\phantom{....}|\\ \ce{H - C - C - H}\\ |\phantom{....}|\\ \ce{H}\phantom{...}\ce{H}\\ \end{array}\] |
| 3. | Propane | \[\begin{array}{cc} \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ |\phantom{....}|\phantom{....}|\\ \ce{H - C - C - C - H}\\ |\phantom{....}|\phantom{....}|\\ \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ \end{array}\] |
