Which of the following statements is not true about the sulfonation of benzene? Heating sulfuric acid leads to formation of the +503H electrophile. Sulfonation is irreversible. Sulfonation occurs through an electrophilic aromatic substitution mechanism. The rate limiting step is formation of a resonance stabilized carbocation intermediate. Sulfonation results in an NO2 group attached to the aromatic ring

Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.
