- B. 6
- C. 7
- D. 8
Explanation
The simplest aromatic aldehyde is benzaldehyde (C6H5CHO). It has a benzene ring with a formyl group (-CHO) attached to it. The benzene ring has 6 carbon atoms and 5 hydrogen atoms. The formyl group contributes one more hydrogen atom. Therefore, benzaldehyde has a total of 6 hydrogen atoms.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
