Question

The organic compounds having close resemblance in structure as well as properties are:

Options
  • A

    Glycol and cyclohexanol

  • B

    Formaldehyde and benzol

  • C

    Diethyl ether and ethyl alcohol

  • D

    Methanal and acetone

Explanation

Methanal is an aldehyde while acetone is a ketone. Both compounds have a similar structure as they contain a carbonyl group. They also show some common reactions such as nucleophilic addition and thus have common properties.

This option is incorrect.Methanal and acetone: Methanal is an aldehyde, and acetone is a ketone. These have different carbonyl group positions and overall structures.so option D is correct

This option is incorrect. Formaldehyde and benzol: Formaldehyde is an aldehyde, while benzol (benzene) is an aromatic hydrocarbon. These have very different structures and properties.

This option is incorrect.* Diethyl ether and ethyl alcohol: Diethyl ether is an ether, and ethyl alcohol is an alcohol. While they both contain oxygen, their functional groups (-O- vs. -OH) lead to different properties.

Methanal is an aldehyde while acetone is a ketone. Both compounds have a similar structure as they contain a carbonyl group. They also show some common reactions such as nucleophilic addition and thus have common properties.
