Purification & Characterisation · Carius method halogen estimation

Sodium fusion extract of an organic compound (Y) with $\ce{CHCl3}$ and chlorine water gives violet color to the $\ce{CHCl3}$ layer. 0.15g of (Y) gave 0.12 g of the silver halide precipitate in Carius method. Percentage of halogen in the compound (Y) is . (Nearest integer).

(Given : molar mass g mol$^{-1}$ C : 12, H : 1, Cl : 35.5, Br : 80, I : 127)
