Chemistry: Atoms First

Write a molecular formula and a structural formula (or condensed structural formula) for the following:

Strategy Count the $\text{C}$ atoms represented and the heteroatoms shown. Determine how many $\text{H}$ atoms are present using the octet rule.

Setup Each line represents a bond. (Double lines represent double bonds.) Count one $\text{C}$ atom at the end of each line unless another atom is shown there. Count the number of $\text{H}$ atoms necessary to complete the octet of each $\text{C}$ atom.
