Reduction of aldehydes and ketones into hydrocarbons using zinc amalgam and conc.

Thus after the deprotonation process the negative charge will be in conjugation with the pi orbital of the formed carbonyl in this case the base will prefer to abstract alpha hydrogen from a ketone. Neet questions solutions with pdf and difficulty level. Hence a hydrogen can be abstracted from ketone with a base. Hcl is called cbse aipmt 2007 a beta hydroxy aldehyde or a beta hydroxy ketone.

Strong bases can deprotonate carbonyl compounds. Although the concentration of enolate may be small as the enolate reacts with an electrophile the equilibrium shifts to the right. Therefore a strong base can abstract an a hydrogen from ketone. Q6 a strong base can abstract an alpha hydrogen from.
