On treatment of propanone with dilute Ba(OH)2 the product formed
aldol
phorone
propionaldehyde
4-hydroxy-4-methyl-2-pentanone
Formation of cyanohydrin from a ketone is an example of
electrophilic addition
nucleophilic addition
nucleophilic substitution
electrophilic substitution
Glycerol on treatment with oxalic acid at 110°C forms
formic acid
allyl alcohol
CO2 and CO
acrolein
The fatty acid which shows reducing property is
acetic acid
ethanoic acid
oxalic acid
formic acid
D.
formic acid
Formic acid (HCO : OH), because of the presence of -CHO group also reduces Tollen's reagent, Fehling solution etc. Thus, it has reducing property.
