Benzaldehyde is converted to benzyl alcohol by

Benzaldehyde (C_6H_5CHO$) is an aldehyde that does not contain any \alpha$-hydrogen atom.

When treated with a concentrated alkali solution, it undergoes a disproportionation reaction (self-oxidation and self-reduction) to form one molecule of benzyl alcohol (C_6H_5CH_2OH$) and one molecule of a salt of benzoic acid (C_6H_5COO^-$).

This reaction is known as Cannizzaro's reaction.

$2C_6H_5CHO + NaOH \rightarrow C_6H_5CH_2OH + C_6H_5COONa$

Wurtz, Fittig, and Wurtz-Fittig reactions are coupling reactions involving alkyl and/or aryl halides in the presence of sodium metal.

Answer: Cannizzaro's reaction
