Solution

The correct option is A 6

2,4-dinitrotoluene or dinitro is an organic compound with the formula CHNO. This pale yellow crystalline solid is well known as a precursor to trinitrotoluene (TNT) but is mainly produced as a precursor to toluene diisocyanate.

Isomers of dinitrotoluene

Six positional isomers are possible for dinitrotoluene. The most common one is 2,4-dinitrotoluene. The nitration of toluene gives sequentially mononitrotoluene, dinitrotoluene, and finally trinitrotoluene. 2,4-DNT is the principal product from dinitration, the other main product being about 30% 1,3-DN2-T. The nitration of 4- nitrotoluene gives 2,4-DNT.

conclusion: hence the option (A) is correct.
