1.	Benzaldehyde is treated with acetaldehyde in presence of dilute alkali. What happens ?
Answer» Solution :When benzaldehyde reacts with ACETALDEHYDE, first unstable `beta` - hydroxy aldehyde is formed which loses a molecule of water to form CINNAMALDEHYDE. `C_6H_5CHO +CH_(3) CHOoverset("dil")underset(NaOH)RARR` `C_6H_5-CH(OH) CH_2CHOoverset("HEAT")underset(-H_2O)rarr C_6H_5-CH=CHCHO`
