A compound X has molecular formula `C_(3)H_(6)`. One mole of X reacts with one mole of bromine to yield a compound Y. Deduce the structures of X and Y.

Explanation

One mole of `X(C_(3)H_(6))` takes one mole of `Br_(2)` so it contains one doubled bond.
`therefore` Structure of X : `underset("(Propene)")(H-overset(H)overset(|)C=overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-H)`
`H-overset(H)overset(|)C=overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-H+Br_(2)rarrunderset("1, 2-Dibromopropane")(H-underset(Br)underset(|)overset(H)overset(|)C-underset(Br)underset(|)overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-H)`
`therefore` Structure of Y : `H-underset(Br)underset(|)overset(H)overset(|)C-underset(Br)underset(|)overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-H`
