Why is a white precipotate obtained for the test for halogenoalkanes
Accepted Answer
A white precipitate forms when a halogenoalkane is reacted with silver nitrate in the presence of aqueous ammonia. This is because the silver halide formed is insoluble in water but soluble in aqueous ammonia. The precipitate color helps identify the halide present: white for chloride, cream for bromide, and yellow for iodide.
