Answer
Correct option: B.
$4-$Methyl cyclo $ -2-$ butene $-1-$ol
b
The parent hydrocarbon is cyclobutanol. (Since alcohol functional group has highest priority)
The parent hydrocarbon is cyclobutanol. (Since alcohol functional group has highest priority)
First carbon has hydroxyl group as substituent.
Fourth carbon has methyl group as substituent.
A double bond is present between second and third carbon atom.
Hence, the IUPAC name of given compound is $4$ - methylcyclobut -$2$ - en -$1$ -ol
