Question

provide the molecular formula for each of the following compounds. part 1 of 3 part 2 of 3

Explanation:

Step1: Count carbon atoms in part 1

The structure in part 1 has 7 carbon atoms.

Step2: Count hydrogen atoms in part 1

Using the rule that each carbon in a saturated - like structure (in a ring or chain) is bonded to 4 atoms, the number of hydrogen atoms is 14. So the molecular formula for part 1 is $C_{7}H_{14}$.

Step3: Count carbon atoms in part 2

The structure in part 2 has 6 carbon atoms.

Step4: Count hydrogen atoms in part 2

There is a double - bond in the structure. Counting the hydrogen atoms based on the valency of carbon (4), the number of hydrogen atoms is 12. So the molecular formula for part 2 is $C_{6}H_{12}$.

Answer:

Part 1: $C_{7}H_{14}$
Part 2: $C_{6}H_{12}$
