Interpretation: The structures of the unknown compounds with the help of the given suitable reagents are to be represented.
Concept introduction: Sodium Borohydride is the reducing agent that converts aldehyde to primary alcohol. Aldehyde forms acetals more readily than
The compound pyridinium chlorochromate denoted by
Acetals can be made easily from the aldehyde as well as ketones. They hydrolyze in the acidic conditions but stable to the attack of strong bases and nucleophiles. Grignard reagents are the organomagnesium halides. They are used as source of carbanions and react with electrophilic centers.
When the aldehyde is protected as an acetal, it does not react with the Grignard reagent. Dilute aqueous acid protonates the alkoxide to give alcohol and hydrolyzes the acetals to give the aldehyde.
In the Clemmensen reduction, the reduction of aldehyde or ketone to
To determine: The structures of the unknown compounds with the help of the given suitable reagents.
