Answer 1

Sr. No.	Structure	IUPAC name	Common name
1.	\[\begin{array}{cc} \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ |\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\\ \ce{H - C - C - C - C - C - H}\\ |\phantom{....}|\phantom{....}|\phantom{....}|\phantom{....}|\\ \ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}\\ \end{array}\]	Pentane	n-pentane
2.	\[\begin{array}{cc} \phantom{..}\ce{CH3}\\ |\\ \ce{CH3 - C - CH3}\\ |\\ \phantom{..}\ce{CH3}\\ \end{array}\]	2, 2 dimethyl propane	Neo-pentane
3.	\[\begin{array}{cc} \ce{CH3}\phantom{........}\\ |\phantom{..........}\\ \ce{Ch3 - CH2 - CH2 - CH2} \end{array}\]	2-methyl butane	Iso-pentane
