A : Ozonolysis of benzene gives ethanal.
R : Benzene is an antiaromatic compound.

Options

A. Glyoxal
B. Glycerine
C. Glycol
D. Glycerol

Answer

A

Explanation

Ozonolysis of benzene yields glyoxal. Benzene adds three molecules of ozone and forms benzene triozonide which of decomposition with water gives three molecules of glyoxal. `underset("benzene")(C_(6)H_(6))+underset("ozone")(3O_(3))rarrunderset("benzene triozonide")(C_(6)H_(6)O_(9)
