Options

  1. A4 - methyl - 3 - ethylhexane
  2. B3 - ethyl - 4 - methylhexane
  3. C4 - ethyl - 3 - methylhexane
  4. D3, 4 - ethylmethylhexane

Correct answer

B. 3 - ethyl - 4 - methylhexane

Step-by-step solution

​ ​3 - ethyl - 4 - methylhexane Longest chain - 6 carbon Substituent present -ethyl and methyl, since ethyl comes alphabeticaly first, hence the numbering will be such that ethyl group get lowest possible number.
