Which of the following hydrocarbon molecules possesses exactly four times as many bonds as bonds?

Step-by-step solution

To find the ratio of to bonds, we determine the number of each type of bond in the given molecules. 1. Benzene ( C ₆ H ₆ ): The structure contains 6 C - C bonds in the ring, 6 C - H bonds, and 3 C = C bonds. Total bonds = 12 . Total bonds = 3 . The ratio is 12:3 = 4:1 . 2. Toluene ( C ₆ H ₅ CH ₃ ): The ring contains 6 C - C bonds and 5 C - H bonds. The methyl group is attached via 1 C - C bond and contains 3 C - H bonds. Total bonds = 6 + 5 + 1 + 3 = 15 . Total bonds in the ring = 3 . The ratio is 15:3 = 5:1 . 3. E
