Select the correct IUPAC name for the following branched alcohol

Select the correct IUPAC name for the following branched alcohol

The Correct Answer and Explanation is :

The IUPAC name for the branched alcohol depicted in the provided image is 2-Ethylhexan-1-ol.

Explanation:

  1. Identifying the Parent Chain:
  • The longest continuous carbon chain containing the hydroxyl group (–OH) is selected as the parent chain.
  • In this case, the parent chain is an eight-carbon chain, corresponding to the alkane octane.
  1. Numbering the Parent Chain:
  • The chain is numbered from the end nearest the hydroxyl group to give it the lowest possible locant.
  • The hydroxyl group is on carbon 1, so the compound is a 1-ol.
  1. Identifying and Naming Substituents:
  • A two-carbon branch (ethyl group) is attached to carbon 2 of the parent chain.
  • The ethyl group is named ethyl.
  1. Constructing the Full Name:
  • The substituent is named first, followed by the parent chain name, and the suffix indicating the functional group.
  • The full IUPAC name is 2-Ethylhexan-1-ol.

Additional Notes:

  • The common name 2-Ethylhexanol is widely used in industry and commerce.
  • This compound is utilized as a plasticizer and solvent in various applications.
