Answer»

ONE and three
two and three
one and two

SOLUTION :`H_2C=CH_2+Br_2rarrBrH_2C-CH_2Br`
`HC-=CH+2Br_2-H-underset(br)underset(|)overset(Br)overset(|)C-underset(br)underset(|)overset(Br)overset(|)C-H`
One mole of cthcnc requires one mole of BROMINE and one mole of ethyne requires two moles of bro mine for Decolourisation
