MCQ
The $IUPAC$ name of the compound   is
  • $trans-2-$ chloro $-3-$ iodo $-2-$ pentene
  • B
    $cis-2-$ chloro $-3-$ iodo $-2-$ pentene
  • C
    $trans -3-$ iodo $-4-$ chloro $-3-$ pentene
  • D
    $cis-3-$ iodo $-4-$ chloro $-3-$ pentene

Answer

Correct option: A.
$trans-2-$ chloro $-3-$ iodo $-2-$ pentene
a
Correct IUPAC name of above compound is trans-$2$-chloro-$3$-iodo-$2-$pentene.

The parent hydrocarbon contains $5 C$ atom continuous chain with one $C = C$ bond between second and third carbon atom.

Hence, it is named as $2$-pentene.

One $Cl$ and one $I$ are present at second and third carbon atom respectively.

The molecule has trans geometry across $C = C$ bond.

Hence, it is named trans-$2$-chloro-$3$-iodo-$2$-pentene.
