$\text{Propanal} + \text{Methanal}$ $\xrightarrow[\text{(ii)}\Delta, \text{(iii)}\text{NaCN}, \text{(iv)}\text{H}_3\text{O}^+]{\text{(i)}\text{dil. NaOH}} \text{Product } B (C_5H_8O_3)$
The correct statement for product $B$ is:

  • A
    optically active and adds one mole of bromine
  • B
    racemic mixture and is neutral
  • C
    racemic mixture and gives a gas with saturated $\text{NaHCO}_3$ solution
