According to IUPAC system, the compound

figure

is named as

  1. Option A:

    Cyclohex-1-en-2-ol

  2. Option B:

    1-Hydroxyhex-2-ene

  3. Option C:

    Cyclohex-1-en-3-ol

  4. Option D:

    Cyclohex-2-en-1-ol

    Correct

Answer: D

Step-by-step solution

In cyclic systems, the OH\mathrm{OH} group gets highest priority. Therefore numbering begins from the carbon bearing OH\mathrm{OH}.

Hence the double bond gets position 22 and the OH\mathrm{OH} group gets position 11.

Thus, the correct IUPAC name is Cyclohex-2-en-1-ol\mathrm{Cyclohex\text{-}2\text{-}en\text{-}1\text{-}ol} .
