1) An organic compound 'A' has the molecular formula C3H6O it undergoes the iodoform test. When saturated with dil. HCl gives 'B' of molecular formula C9H14O. A and B respectively are A) Propanal and mesitylene B) Propanone and mesityl oxide C) Propanone and 2,6- dimethyl-2, 5-heptadien-4-one D) Propanone and mesitylene oxide Answer: Option CExplanation:Compound A with formula C3H6O gives an iodoform test, it is propanone. It forms a compound B having carbon atoms three times to the number of carbon atoms in propanone, it is 2, 6-dimethyl-2, 5-heptadien-4-one.
