• A.

  NaCN
  (ii) HO⁻, H₂O
  

  (iii) H₃O⁺
• B.

  CHO
  (CHOH)₄
  CH₂OH
  

  Br₂, H₂O
• C.

  Br (i) KOH, EtOH
  (ii) KMnO₄, H₂SO₄, Δ
  

• D. H₂CrO₄

Answer 1

Answer: (C)

C

Answer 2

The correct answer is C. The reaction sequence in option C involves the conversion of an alkyl halide to an alkyne, followed by oxidation of the alkyne to a dicarboxylic acid using KMnO₄ under acidic conditions and heat.
