Iodoform gives a precipitate with `AgNO_3` on heating while chlofrom does not why?

Will C Cl_4 give white precipitate of AgCI on heating it with AgNO_3 ?Give reason of your answer.

An organic compound has the molecular formula C_5H_(10)O . The compound does not reduce Tollen's reagent but reacts with Brady's re-agent to give orange precipitate. On vigorous Oxidation, the molecule produces ethanoic acid and propanoic acid. The com-pound also gives iodoform test. Identify the compound and write equations for chemical reactions involved.

An organic compound contains 69.77% carbon, 11.63% hydrogen and the rest is oxygen. The molecular mass of the compound is 86u. The compound does not reduce Tollens reagent but reacts with Brady's reagent to give yellow precipitate. On vigorous oxidation the molecule produces ethanoic acid and propanoic acid. The compound also shows iodoform test. Identify and name the compound and write the reactions.

CIF_3 exists but FCI_3 does not why?

Explain why Water on a clean glass surface tends to spread out while mercury on the same surface tends to form drops. (Put differently, water wets glass while mercury does not.)

Why does the cord of an electric heater not glow while the heating element does?

An optically active amide (A)C_5H_(11)NO on acid hydrolysis gives an acid and NH_3 . When (A) is treated with bromide and alkali a compound is obtained which one treatment with nitrous acid gives an optically active alcohol and nitrogen. The alcohol gives positive iodoform test. What is the structure of A and show the reactions involved.
