$\text{CH}_3\text{−C​H}​\text{−C​H}​−\text{CH}_​3\\ \ \ \ \ \ \ \ \ \ \ \ \ | \ \ \ \ \ \ \ \ \ \ | \\ \ \ \ \ \ \ \ \ \ \text{OH}\ \ \ \ \ \ \text{OH}\\\\\\\text{IUPAC}$ name of the given compound is:
  • ✓
    Butane$-2, 3-$diol
  • B
    $1-$Methyl$-$propane$-1, 2-$diol
  • C
    Both $(A)$ and $(B)$
  • D
    None of these
✓

Answer

Correct option: A.
Butane$-2, 3-$diol
Two functional group $\ce{OH(ol)}$ is attached at carbon no $2 \ \ \ 3$ so its name is butane$−2,3−$diol.
