Which statement about tautomerism is correct?

Correct answer: C. Have same molecular formula

  • A. Only occurs in organic compounds
  • B. Not influenced by temperature
  • C. Have same molecular formula
  • D. Have different molecular formula
  • E. Identical chemical properties

Explanation

Tautomers are a specific type of isomerism characterized by having the same molecular formula but differing in the connectivity of atoms, specifically the position of a proton and a double bond. This means that while they share the same chemical composition, their structural differences can lead to variations in their chemical behavior and properties.Option A is incorrect as tautomerism is not limited to organic compounds alone. Option B is incorrect because temperature can influence the equilibrium between tautomers. Option D is wrong since tautomers must have the same molecular formula, and Option E is misleading as tautomers can exhibit different chemical properties despite having similar structures.
