Question

A reagent used to test for unsaturation of alkene is (A) cone. H2SO4  (B) ammoniacaI Cu2Cl2  (C) ammoniacal AgNO3  (D) solution of Br2 in CCl4

Tardigrade Admin · Accepted Answer

Ammoniacal AgNO3 and ammoniacal cuprous chloride are used to test the presence of terminal alkyne. Br2 in CCl4 is used to test the presence of unsaturation in organic compound. Organic compounds having double or triple bond decolourise the reddish/brown + colour of bromine water.

cone. $H_{2} S O_{4}$

ammoniacaI $C u_{2} C l_{2}$

ammoniacal $A g N O_{3}$

solution of $B r_{2}$ in $CC l_{4}$

Ammoniacal $A g N O_{3}$ and ammoniacal cuprous chloride are used to test the presence of terminal alkyne. $B r_{2}$ in $CC l_{4}$ is used to test the presence of unsaturation in organic compound. Organic compounds having double or triple bond decolourise the reddish/brown + colour of bromine water.
