Question

Identify the product formed in the following reaction:

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is C

The given reaction involves a halogenoalkane reacting with aqueous sodium hydroxide (\text{NaOH (aq)}). This is a common nucleophilic substitution reaction where the halogen atom (in this case, chlorine) is replaced by a hydroxyl group (-\text{OH}), resulting in the formation of an alcohol.

1. The halogenoalkane depicted in the image is cyclohexyl chloride.
2. The mechanism follows an SN₁ pathway if the substrate is bulky or an SN₂ pathway if it is less hindered. In this case, the cyclohexyl moiety allows for direct substitution as it is fairly unhindered.
3. Aqueous sodium hydroxide acts as a source of hydroxide ions (\text{OH}^–), which are strong nucleophiles.
4. The nucleophile attacks the electrophilic carbon atom bonded to the chlorine, resulting in the chlorine being displaced and forming cyclohexanol.

The product of the reaction is cyclohexanol:

This matches the correct answer option provided.
