Question

The number of single bonds and double bonds present in a structure of benzene
molecule respectively
A. 6 and 6
B. 9 and 3
C. 7 and 5
D. 3 and 9​

Answer 1

Answer:

B)9 and 3

Explanation:

Six single bonds between Carbons and Hydrogens, three single bonds between six Carbons and Hydrogens ( alternatively) . Three double bonds present between carbons ( alternatively in hexagonal ring). So a total of nine single bonds, three double bonds are present in benzene ring.

Answer 2

Answer:

The correct answer is option B. 9 and 3.

Concept:

Unsaturated and cyclic organic compounds or hydrocarbons.

Explanation:

Benzene ($C_6H_6$) is an aromatic organic compound that falls under the category of unsaturated hydrocarbons (Hydrocarbons containing one or more double bonds).

The IUPAC name of Benzene is "Cyclohexa-1,3,5-triene". Cyclo- here means it is a closed structure or we can say it is a cyclic hydrocarbon.

The structure of benzene is shown below and clearly, we can see that it contains a total of 9 single bonds including bonds with hydrogen atoms and 3 double bonds.

There are total 6 carbon atoms and 6 hydrogen atoms present in benzene. As benzene is a cyclic organic compound that forms a ring, so it is commonly known as "benzene ring".
