Answer 2

REACTION OF FURAN WITH CHLOROFORM IN POTASSIUM HYDROXIDE WILL FORM FURFURAL.

Explanation:

• An unsaturated hydrocarbon undergoes Reimer Teimann reaction with chloroform in presence of a base to form a carbene intermediate.
• Ortho-formylated products are formed from phenols, when they undergo Reimer Teimann reaction.
• The reaction of furan with chloroform and KOH will form a carbene intermediate first, then hydroxide ion attacks the carbon of carbene and it will lose chlorine atoms to form a ⇒ furfural.
• Therefore, reaction of furan with chloroform/KOH will give furfural.
