General Organic Chemistry Question 13

Question 13 - 31 January - Shift 1

Consider the following reaction

$ \text{ Propanal + Methanal = } \xrightarrow[\substack{\text{ (ii) } \Delta \\ \text{ (iii) } NaCN^{+} \\ \text{(iv) } H_3 O^{+}}]{\text{(i) dil. } NaOH} \underset{\text{ Product } B}{(C_5 H_8 O_3)} $

The correct statement for product B is. It is

(1) optically active and adds one mole of bromine

(2) racemic mixture and is neutral

(3) racemic mixture and gives a gas with saturated

$NaHCO_3$ solution

(4) optically active alcohol and is neutrall
