Passage / Comprehension
Nucleophilic addition reaction is an addition reaction where a chemical compound with an electrophilic double bond reaction with nucleophile.
The number of Cannizaro reaction(s) that occurs in the given transformation is
Options:
Answer:
A
Solution:
Cannizzaro reaction occurs with aldehydes having no α-hydrogen in presence of conc. NaOH.
In the given mixture, only Formaldehyde undergoes Cannizzaro reaction because it has no α-H.
Acetaldehyde has α-hydrogen, so it does not show Cannizzaro reaction and instead prefers aldol reaction.
Thus, only one aldehyde molecule participates in Cannizzaro reaction in the whole transformation.
Hence, the number of Cannizzaro reactions occurring is one.
