Name the final product of ammonolysis of an alkyl halide. 

Explanation

The process of cleavage of the C-X bond of halo alkane by ammonia is called ammonolysis. This reaction is carried out in a sealed vessel at 373 K.
`underset(1^(@)" amine")(R-NH_(2))overset(R-X)rarr underset(2^(@)-" amine")(R_(2)-NH)overset(R-X)rarr underset(3^(@)" amine")(R_(3)-NH) overset(R-X)rarr underset("ammonium salt")underset("Quaternary")(R_(4)-N^(+)H^(-))`
The final product of ammonolysis of an alkyl halide is quaternary ammonium slat.
