Answer
Draw a carbon wherever two lines meet and, a line begins and ends. And then add the number of hydrogens so that each carbon has four bonds.
The molecular formula is $C_6H_{13}N$
Work Step by Step
1) Draw a carbon wherever two lines meet and, a line begins and ends.
2) Draw a bond between nitrogen and hydrogen, and a lone pair on nitrogen.
3) Then add the number of hydrogens so that each carbon has four bonds.
4) Count the number of C, H and N. In this structure there are 6 Carbons, 13 hydrogens and 1 nitrogen. Thus the molecular formula is $C_6H_{13}N$
