The IUPAC name for the following compound is BrCH ₂ CH ₂ CH = CHCH ₂ COCH ₃

Options

  1. A1-bromohept-3-en-6-one
  2. B2-oxo-bromohept-4-one
  3. C7-bromo-2-oxohept-4-one
  4. D7-bromohept-4-en-2-one

Correct answer

D. 7-bromohept-4-en-2-one

Step-by-step solution

Carbonyl group has more priority than double bond and bromine, so numbering should be start from carbonyl side. Br ^7 -6 C H ₂ 5 C H ₂ 4 C H = 3 C H 2 C H ₂^ C O 1 C H ₃ Thus, the correct IUPAC name of the given compound is 7-bromohept-4-en-2-one. Hence, the correct option is (4).
