MCQ
To distinguish between formaldehyde and acetaldehyde, we require
- ATollen's reagent
- BFehling's solution
- CSchiff's reagent
- ✓Caustic soda solution
✓
Answer
Correct option: D.
Caustic soda solution
d
(d) $2HCHO\mathop {\xrightarrow{{NaOH}}}\limits_{Conc.} C{H_3}OH + HCOONa$
(d) $2HCHO\mathop {\xrightarrow{{NaOH}}}\limits_{Conc.} C{H_3}OH + HCOONa$
It is aldol condensation reaction.
$2C{H_3}CHO\mathop {\xrightarrow{{NaOH}}}\limits_{dil} C{H_3} - \mathop {\mathop {CH}\limits^{|\,\,\,\,\,\,} }\limits^{OH} - C{H_2} - CHO$
It is aldol condensation reaction.
