- A$1-$ methyl $-3-$ ethykyclohexene
- ✓$5-$ ethyl $-1 -$ methylcyclohexene
- C$2- $ ethyl $-4-$ methylcyclohexene
- D$3-$ ethyl $-1-$ methylcyclohexene
✓
Answer
Correct option: B.
$5-$ ethyl $-1 -$ methylcyclohexene
b
here, numbering is done in such a way that double bond gets first priority along wih lowest number to the locants.
$\therefore$ There are $2$ substituents ethyl and methyl.
$IUPAC$ name $: 5-$ ethyl $-1-$ methyl cyclohexene
