What is the major product obtained when tert-butyl bromide is heated with silver fluoride?

Options:

Answer:

Solution:

The reaction of an alkyl chloride or bromide with a metallic fluoride such as $A g F$ , $H g_{2} F_{2}$ , $C o F_{2}$ , or $S b F_{3}$ to form an alkyl fluoride is known as the Swarts reaction.

When tert-butyl bromide (2-bromo-2-methylpropane) is heated with silver fluoride ( $A g F$ ), the bromine atom is substituted by a fluorine atom.

$(C H_{3})_{3} C - B r + A g F Δ (C H_{3})_{3} C - F + A g B r$

The product formed is tert-butyl fluoride, whose IUPAC name is 2-fluoro-2-methylpropane.

Answer: 2-Fluoro-2-methylpropane
