Which among the following is not a property of aromatic hydrocarbon:a)...
Explanation:
Aromatic hydrocarbons are a class of organic compounds that contain one or more benzene rings. These compounds exhibit unique properties due to the presence of aromaticity in their structure.

Properties of Aromatic Hydrocarbons:
  • Excellent Aromaticity: Aromatic hydrocarbons exhibit very good aromaticity due to the presence of conjugated pi electrons in the benzene ring. This aromaticity contributes to their stability and reactivity.
  • Excellent Stability: Aromatic hydrocarbons are known for their high stability compared to non-aromatic compounds. The delocalization of electrons in the benzene ring leads to a lower energy state, making these compounds less reactive.
  • Strong Carbon-Hydrogen Ratio: Aromatic hydrocarbons have a strong ratio between carbon and hydrogen atoms in their structure. This ratio is a characteristic feature of aromatic compounds and contributes to their stability.



Not a Property of Aromatic Hydrocarbons:
  • Do not undergo Nucleophilic Substitutions: Aromatic hydrocarbons do not undergo nucleophilic substitutions due to the stability of the benzene ring. However, they undergo electrophilic substitutions where an electrophile attacks the aromatic ring and substitutes a hydrogen atom.


Therefore, the statement "These compounds do not undergo nucleophilic substitutions but they undergo electrophilic substitutions" is not a property of aromatic hydrocarbons, as they do undergo electrophilic substitutions.
