IUPAC name of following compound (P) is :

Options

  1. A1 - Ethyl - 5 , 5 - dimethylcyclohexane
  2. B3 - Ethyl - 1 , 1 - dimethylcyclohexane
  3. C1 - Ethyl - 3 , 3 - dimethylcyclohexane
  4. D1 , 1 - Dimethyl - 3 - ethylcyclohexane

Correct answer

B. 3 - Ethyl - 1 , 1 - dimethylcyclohexane

Step-by-step solution

By IUPAC nomenclature, The parent chain in this compound is the cyclohexane ring, which consists of six carbon atoms. The substituents are: Ethyl group attached to third carbon. Two methyl groups attached to carbon 1 . The Numbering must be given the carbons in the cyclohexane ring so that the substituents get the lowest numbers, Hence, the name is 3 -ethyl 1 , 1 -dimethylcyclohexane
