Question

Which of the following reactions will not result in the formation of carbon-carbon bonds?

• A. Cannizaro reaction
• B. Wurtz reaction
• C. Reimer-Tiemann reaction
• D. Friedel-Crafts acylation

Answer 1

The correct option is A Cannizaro reaction

$HCHO\stackrel{conc.NaOH}{\to }HCO{O}^{-}N{a}^{+}+C{H}_{3}OH$ (Cannizaro reaction)

$R-Cl\underset{dryether}{\overset{Na}{\to }}R-R+NaCl$ (Wurtz reaction)

Cannizaro reaction will not result in the formation of carbon-carbon bonds. Cannizaro reaction is disproportionation reaction in which one molecule of carbonyl compound is oxidized to sodium salt of carboxylic acid and other molecule is reduced to alcohol.
