According to IUPAC system, the compound is named as:

Options

  1. ACyclohex - 1 - en - 2 - ol
  2. B1 - Hydroxyhex - 2 - ene
  3. CCyclohex - 1 - en - 3 - ol
  4. DCyclohex - 2 - en - 1 - ol

Correct answer

D. Cyclohex - 2 - en - 1 - ol

Step-by-step solution

The structure of the IUPAC compound is Secondary prefix+ primary prefix + root word + Primary suffix + Secondary suffix It is a cyclic compound, with one OH group on position 1 and double bond at position 2 . There is no secondary prefix in the above compound. primary prefix is cyclo. Root word is hex, primary suffix is en and secondary suffix is ol. Hence, the name is Cyclohex-2-en-1-ol.
