Among H - CHO , CH ₃ CHO and C ₆ H ₅ CHO , which will undergo Cannizaro's reaction?

Options

AHCHO and CH ₃- CHO
BCH ₃- CHO and C ₆ H ₅ CHO
CC ₆ H ₅ CHO and HCHO
DAll of the above

Correct answer

C. C ₆ H ₅ CHO and HCHO

Step-by-step solution

Cannizaro reaction is possible in which aldehyde where the -hydrogen atoms are absent. e.g. HCHO , C ₆ H ₅ CHO 2 HCHO - [ ] NaOH HCOONa + CH ₃ OH aligned 2 C ₆ H ₅ CHO - NaOH & C ₆ H ₅ & CH ₂ OH & + C ₆ H ₅ COONa aligned
