Molar mass of the hydrocarbon (X) which on ozonolysis consumes one mole of O 3 per mole of (X) and gives one mole each of ethanal and propanone is ______ g mol –1 (Molar mass of C : 12 g mol –1 , H : 1 g mol –1 )

Question

Molar mass of the hydrocarbon (X) which on ozonolysis consumes one mole of O 3 per mole of (X) and gives one mole each of ethanal and propanone is ______ g mol –1 (Molar mass of C : 12 g mol –1 , H : 1 g mol –1 ),

MARKS App · Accepted Answer

When 2-methyl butene-2 is subjected to ozonolysis and then reduced in presence of dimethyl sulphide or Zn dust, it yields acetone and acetaldehyde. Cycloaddition of a molecule of ozone occurs first and then it is cleaved reductively to give aldehyde and ketone.
