Question

Turpentine oil undergoes complete combustion reaction with chlorine to produce compound X. The number of lone pairs in X is:

(a) 0
(b) 1
(c) 2
(d) 3

Answer 1

Turpentine oil undergoes complete combustion reaction with chlorine to produce compound X. The number of lone pairs in X is 2.

Option C is correct.

The combustion reaction of turpentine oil (a hydrocarbon) with chlorine typically leads to the formation of chlorinated hydrocarbons. Chlorine (Cl2) can replace hydrogen atoms in the hydrocarbon structure.

The general formula for a chlorinated hydrocarbon can be represented as follows:

Hydrocarbon +
`Cl_2` + → Chlorinated Hydrocarbon + HCl

In the chlorinated hydrocarbon, the chlorine atoms replace hydrogen atoms in the hydrocarbon structure. Chlorine usually forms a single bond with carbon. Therefore, each chlorine atom adds one lone pair to the carbon it is bonded to.
