In Carius method of estimation of halogen, 0.25 g of an organic compound gave 0.15 g of silver bromide (AgBr). The percentage of Bromine in the organic compound is ____ times 10^-1$\times 10^{-1}$ % (Nearest integer). (Given : Molar mass of Ag is 108 and Br is 80 g mol ^-1$^{-1}$)

### Core Logic The fundamental principle used in chromatography (such as column chromatography or thin-layer chromatography) is adsorption. Different components of a mixture are adsorbed to different extents on an adsorbent stationary phase. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 11 Chemistry: Organic Chemistry - Some Basic Principles and Techniques

### Core Logic (A) Simple distillation is used to separate a mixture of miscible liquids with a sufficiently large difference in their boiling points, such as chloroform and aniline. (A rightarrow$\rightarrow$ IV) (B) Fractional distillation is used to separate crude oil fractions. (B rightarrow$\rightarrow$ III) (C) Steam distillation is used to separate steam-volatile substances that are immiscible with water, like an aniline-water mixture. (C rightarrow$\rightarrow$ II) (D) Distillation under reduced pressure is used for liquids that decompose at or below their normal boiling points, like separating glycerol from spent lye. (D rightarrow$\rightarrow$ I) ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 11 Chemistry: Organic Chemistry - Some Basic Principles and Techniques
