Question

An alcohol with $D.U$ $=1$ exists having a $2^o$ hydroxy group with the molecular formula of $C_3{H}_{6}O$ is:

• A. isopropanol
• B. propenol
• C. cyclopropenol
• D. cyclopropanol
  

Answer 1

The correct option is D cyclopropanol

$D.U$ $=1$

$1D.U.$ suggests unsaturated alcohol or cyclic $2^o$ alcohol with three $C$ atoms; $2^o$ alcohol cannot be unsaturated, so it is cyclic.

Hence, option $D$ is correct
