A chloro compound "A". (i) forms aldehydes on ozonolysis followed by the hydrolysis. (ii) when vaporized completely 1 . 53   g of A , gives 448   mL of vapour at STP. The number of carbon atoms in a molecule of compound A is

Step-by-step solution

448   mL of A gives 1 . 53   g of A 22400   mL gives 1 . 53 448 × 22400   g of A = 76 . 5   g CH 3 - CH = CH - Cl → O 3 ,   Zn / H 2 O CH 3 CHO (aldehyde) CH 3 - CH = CH - Cl has 3   -carbon atoms and molecular mass = 76 . 5 .
