What type of salt is Ammonium Chloride?

Explanation

The reactions indicate that both the compounds (A) and (B) are the halogen derivatives of butane and may be expressed as `C_4 H_9 X,` where X = Cl, Br or I.
` underset((A) or (B ) )(C_4 H_9 X) + 2H overset(Zn Cu )to underset("Butane ")(C_4 H_(10)) +HX`
The compound (B) yields 3, 4-diethylhexane when subjected to Wurtz reaction. Hence, compound (B) should be sec-butyl halide and the reaction could be written as
`underset("sec-butyl halide (B)")(CH_3 -CH_2- underset(CH_3) underset(|) CH -X +2Na + X - underset(CH_3) underset(| )(CH )-CH_2 -CH_3) overset("Ether")to underset("3,4-dimethylhexane")(CH_3 -CH_2- underset(CH_3 ) underset(|) (CH ) - underset(CH_3) underset(| )(CH ) -CH_2 -CH_3 +2NaX.`
