Solution

Swarts reaction : It is one of the best rxn. to produce fluoroalkane. When alkyl chloride / alkyl bromide is heated in presence of metallic fluoride ( such as $A g F, H g_{2} F_{2}, C o F_{2}$ etc ), alkyl fluoride is produced
ex. $C H_{3} C H_{2} C l + A g F \to C H_{3} C H_{2} F + A g C l$
The Wurtz reaction, is a coupling reaction whereby two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane
$C H_{3} C H_{2} C l + N a (d r y e t h e r) \to C H_{3} C H_{2} C H_{2} C H_{3} + N a C l$
Finkelstein reaction is the treatment of a primary alkyl halide with an alkali metal iodide (e.g. KI) that leads to replacement of the halogen via an SN2 Reaction with I
$C H_{3} C H_{2} C l + K I \to C H_{3} C H_{2} I + K C l$
