Reagents which cannot be used to distinguish Allylbromide from n - propyl bromide are

Answer»

`Br_2//"CCl"_4`
Shaking with an aqueous solution of `AgNO_3`
Boiling with alcoholic KOH solution followed by acidification with `HNO_3`and ADDITION of `AgNO_3`solution
FUSION with sodium metal followed by acidification with dil `HNO_3`and addition of `AgNO_3` solution

Solution :a) `Br_2//"CCl"_4` can decolourise both allyl BROMIDE and n-propyl bromide as they contain double bond
b) Shaking with `AgNO_3` - Both can react with` AgNO_3`and can form AgBr an yellow ppt
c) Boiling with alcoholic KOH, followed by acidification with `HNO_3`and addition of `AgNO_3` gives same product of yellow ppt of AgBr
d) Fusion with sodium metal followed by acidification with dil `HNO_3`and addition of `AgNO_3`gives an yellow ppt of AgBr
