Paragraph: P and Q are isomers of dicarboxylic acid C ₄ H ₄ O ₄ . Both decolorize Br ₂ / H ₂ O . On heating, P forms the cyclic anhydride. Upon treatment with dilute alkaline KMnO ₄, P as well as Q could produce one or more than one from S , T and U . Question: Compounds formed from P and Q are, respectively

Options

  1. AOptically active S and optically active pair (T,U)
  2. BOptically inactive S and optically inactive pair (T,U)
  3. COptically active pair (T,U) and optically active S
  4. DOptically inactive pair (T,U) and optically inactive S

Correct answer

B. Optically inactive S and optically inactive pair (T,U)
