Question

The products of the reaction of HCHO and PhCHO in presence of concentrated base are (A) HCH2OH+PhCOO- (B) HCOO-+PhCH2OH (C) PhCOOCH3 (D) HCOOCH2Ph

Tardigrade Admin · Accepted Answer

The reaction of an aldehyde with formaldehyde and aqueous base in known as crossed-Cannizzaro reaction. It is formaldehyde rather than the other aldehyde that undergoes oxidation.

HCHO + PhCHO

\to

H CO O^{-} + P h C H_{2} O H

Q. The products of the reaction of HCHO and PhCHO in presence of concentrated base are

$H C H_{2} O H + P h CO O^{-}$

$H CO O^{-} + P h C H_{2} O H$

$P h COOC H_{3}$

$H COOC H_{2} P h$

The reaction of an aldehyde with formaldehyde and aqueous base in known as crossed-Cannizzaro reaction. It is formaldehyde rather than the other aldehyde that undergoes oxidation.

HCHO + PhCHO $\to$ $H CO O^{-} + P h C H_{2} O H$

Q. The products of the reaction of HCHO and PhCHO in presence of concentrated base are

HCH2​OH+PhCOO−

HCOO−+PhCH2​OH

PhCOOCH3​

HCOOCH2​Ph

The reaction of an aldehyde with formaldehyde and aqueous base in known as crossed-Cannizzaro reaction. It is formaldehyde rather than the other aldehyde that undergoes oxidation. HCHO + PhCHO → HCOO−+PhCH2​OH

$H C H_{2} O H + P h CO O^{-}$

$H CO O^{-} + P h C H_{2} O H$

$P h COOC H_{3}$

$H COOC H_{2} P h$
