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
Show Answer
Answer: (3)
Solution:
Formula: Cross Aldol Condensation
$CH_3-CH_2-CHO+HCHO \xrightarrow[\Delta]{OH^{-}}$
(土)
Carboxylic acid will give $CO_2$ gas, with $NaHCO_3$ solution
