Sr. No.	Structural formulae	IUPAC name
1.	\[\begin{array}{cc} \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ |\phantom{....}|\phantom{....}|\phantom{....}|\\ \ce{H - C - C - C - C - H}\\ |\phantom{....}|\phantom{....}|\phantom{....}|\\ \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ \end{array}\]	Butane
2.	\[\begin{array}{cc} \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ |\phantom{....}|\phantom{....}|\\ \ce{H - C - C - C - H}\\ |\phantom{....}|\phantom{....}|\\ \ce{H}\phantom{....}|\phantom{....}\ce{H}\\ \ce{H - C - H}\\ |\\ \ce{H}\\ \end{array}\]	2-methyl propane
