amine reacts with benzene sulfonyl chloride and produces N- phenylbenezesulfonaamide.
chemical reaction is shown in figure.

we know,  If the sulfonamide that dissolves in aqueous sodium hydroxide solution, it is a primary amine. If the sulfonamide is insoluble in aqueous sodium hydroxide, it is a secondary amine.

A/C to question,
sulfonamide dissolve in aqueous solution of sodium hydroxide, NaOH. so, it must be primary amine.

hence, unknown organic compound is amine.

Answer :-

primary amine.

Benzene sulphonyl chloride (C₆H₅SO₂Cl) is also called as Hinsberg's reagent. 

Amines are the organic compounds that can be detected by the Hinsberg's reagent.

The amines are allowed to react with the Hinsberg's reagent or the benzene sulfonyl chloride. If a product is formed, the amine should be either a primary amine or a secondary amine.

It will definitely not be a tertiary amine as tertiary amines will not form any stable sulfonamides.

If the formed sulfonamide gets dissolved in aqueous sodium hydroxide solution, then it will be a primary amine only. This is because the sulfonamide of the primary amine called as the N-alkylsulfonamide has an acidic Hydrogen that is present with its nitrogen.

When it reacts with aqueous NaOH, it will form a sodium salt and therefore, the N-alkylsulfonamide will get dissolved in the NaOH.
