The number of bromine molecles required for the Decolurisation of 1 mo

1.	The number of bromine molecles required for the Decolurisation of 1 mole of ehtene and etyne are respectivelyA. one and threeB. two and threeC. one and twoD. two and four
Answer» `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
