Assertion :The -As=As- linkage present in arsphenamine (a sulpha drugs) resemles the -N=N- linkage present is azo dyes. Reason: The first antibacterial agent, prontosil resembles in structure to the compound salvarsan.

Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- Sulfa drug, also called sulfonamide, any member of a group of synthetic antibiotics containing the sulfanilamide molecular structure. Sulfa drugs were the first chemical substances systematically used to treat and prevent bacterial infections in humans.
- Paul Ehlrich a German bacteriologist was investigating Arsenic based structures in order to produce less toxic substances for the treatment of syphilis. He developed the medicine, arsphenamine, known as salvarsan.Salvarsan is not a sulpha drug.
- Ehrlich was working on azodyes. The –As = As– linkage present in arsphenamine resembles the –N = N – linkage present in azodyes in the sense that arsenic atom is present in place of nitrogen.
- He also succeeded in preparing the first effective antibacterial agent, prontosil, which resembles in structure to the compound, salvarsan.
- Hence,both Assertion and reason are correct but reason is not correct explanation for assertion.
