Question

hydrocarbon X and Y having molecular formula C3 h8 and C3 H6 respectively both are burnt in different specular on the bunsen flame indicate the colour of the flame produced by X and Y write the structural formula

Answer 1

'X' is Propane & 'Y' is Propene .

X is saturated, while Y is unsaturated compound.Unsaturated compounds gives a sooty flame with lot of smoke & Saturated compounds give clean flame.Therefore X will give clean flame & Y will give Sooty flame .

hope it would be helpful

pls pls pls....

mark me as brain list....

Answer 2

HEY MATE...
HERE'S YOUR ANSWER...

X has moleculor formula C3H8
which is of propane, which is a saturated hydrocarbon. whereas Y has molecular formula C3H6 which is of propene which is unsaturated hydrocarbon. moreover saturated hydrocarbon burns completely with blue flame and unsaturated hydrocarbon burns incompletely with yellow flame. thus x burns with blue flame ( saturated hydrocarbon )and y (unsaturated hydrocarbon ) burns with yellow flame.

structural formula of
X and y are in attachment
