Q5 / 90 · JEE Main 2023 (31 Jan Shift 2) · Chemistry

A hydrocarbon 'X' with formula C6H8 uses two moles of H2 on catalystic hydrogenation of its one mole. On ozonolysis, 'X' yields two moles of methane dicarbaldehyde. The hydrocarbon 'X' is :

  • A
    hexa-1, 3, 5-triene
  • B
    1-methylcyclopenta-1, 4-diene
  • C
    cyclohexa-1, 3-diene
  • Correct answer
    D
    cyclohexa-1, 4-diene

Solution

A hydrocarbon X with formula C6H8 uses two moles of H2 on catalystic hydrogenation of its one mole. On ozonolysis,  X yields two moles of methane dicarbaldehyde. The hydrocarbon is cyclohexa-1,4-diene.
