Which one of the following formulae does not represent an organic compound ?
C4H10O4
C4H6O4
C4H7ClO4
C4H9O4
The test for unsaturation is confirmed by the decolourisation of which of the following ?
Iodine water
CusO4 solution
Bromine water
All of these
C.
Bromine water
By adding bromine water to a solution, if the colour of bromine water decolourise then the compound is unsaturated. This is a confirmatory test for unsaturation.
