Question

Which solvent is used in Friedel Crafts reaction?

Answer 1

Friedel Crafts reaction

• A Friedel-Crafts reaction is a type of organic coupling reaction that uses an electrophilic aromatic substitution to attach substituents to aromatic rings.
• There are two types of reaction:
• Alkylation and
• Acylation.
• A commonly used solvent for Friedel craft reaction is Nitrobenzene.
• As per the requirement solvent should be inert ( doesn't react) and should have a high boiling point.
• Due to the presence of nitro group ( electron-withdrawing) on the benzene ring, Nitrobenzene is deactivated and as a result, it becomes almost inert ( towards electrophilic substitution).
• Along with this it also has a high boiling point, 210.9 degrees, due to which it can withstand high temperatures (heating).
