MCQ
Write the IUPAC name of the given compound:

$\text{HO}−\text{CH}_2​−\text{​CH}−\text{CH}_2​−\text{OH}​\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ∣ \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{CH}_3​​$

  • A
    2-Methylpropane-1,3-diol
  • B
    2-Methylpropan-1,3-dial
  • C
    1-Hydroxy-2-methylpropan-1-ol
  • D
    None of these

Answer

  1. 2-Methylpropane-1,3-diol

Explanation:

The given compound can be numbered from left to right or vice versa. At the 2nd position, there is a methyl group and is designated as 2-Methyl.

The parent carbon chain contains 3 carbon atoms resembling propane and at the positions 1 and 3, there's the hydroxyl group designated as 1, 3-diol.

So the IUPAC name of the given compound is 2-Methylpropane-1, 3-diol.
