Question

Ozonolysis of a hydrocarbon gives one mole of acetone and one mole of formaldehyde. The hydrocarbon is (A) propene (B) 2-methylpropene (C) 2-methyl-2-butene (D) 2-methyl-1-butene

Tardigrade Admin · Accepted Answer

As formaldehyde has one carbon atom and acetone has three carbon atoms, thus, the alkene must have four carbon atoms,

i . e .,

2 -

methyl propene.
