The reaction of Hinsberg’s reagent with Isopropylamine gives N-isopropylbenzene sulphonamide. The lone hydrogen attached to the N atom is strongly acidic due to the presence of strong electron withdrawing sulphonyl group. Hence, is it soluble in alkali like KOH.

Which of the following amines will form a product that is soluble in K...
Isopropylamine will form a product that is soluble in KOH with Hinsberg’s reagent:
Isopropylamine is a primary amine, which reacts with Hinsberg’s reagent to form a water-soluble sulfonamide. This reaction involves the substitution of the amino group in the amine with the sulfonyl group in the Hinsberg’s reagent.

Explanation:
- Isopropylamine is a primary amine, which means that it has a hydrogen atom attached to the nitrogen atom.
- When isopropylamine reacts with Hinsberg’s reagent (benzenesulfonyl chloride), the nitrogen atom in isopropylamine undergoes nucleophilic attack by the sulfonyl chloride group.
- This results in the formation of a sulfonamide derivative, where the sulfonyl group replaces the amino group in isopropylamine.
- The sulfonamide derivative formed from isopropylamine is water-soluble, as the sulfonamide group is polar and can interact with water molecules through hydrogen bonding.
- On the other hand, diethylamine, N,N-dimethylpropylamine, and N,N-dimethylaniline are not able to form water-soluble products with Hinsberg’s reagent, as they do not react in the same way as primary amines.
- Therefore, only isopropylamine among the given options will form a product that is soluble in KOH when reacted with Hinsberg’s reagent.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Reactions can occur at different speeds.Reason: Rate of reaction is also called speed of reaction.
