Name two types of carbon-containing molecules that are not organic.

Determine the total hardness as CaCO3 of a sample of water that contains 0.81 mg/L of Ca(HCO3)2 and 0.73 mg/L of Mg(HCO3)2. Equivalent weights of Ca(HCO3)2 and Mg(HCO3)2 are 81.10 g/mol and 73.17 g/mol, respectively.

Nitrogen in organic compound is tested by the addition of few drops of saturated iron (III) sulphate solution to small portion of sodium fusion filtrate. Diluted hydrogen tetraoxosuphate (VI) is then added to the later solution leading to the formation of Prussian blues colour or ppt. signalling the presence of nitrogen. Show these steps using equations and names your final product.

A 3.1g sample of unknown organic gas molecule compose of carbon, hydrogen and oxygen undergoes complete combustion to produce 4.4g CO2 and 2.7g H2O. Calculate the empirical and molecular formula of the gas if the molar mass is 62g/mol.

Why does 3 bromo 3 ethyl heptane give no reaction with potassium hydroxide but bromo propane does

Give reasons why 3- bromo -3- ethyl heptane give no reaction with potassium but bromo-propane

Give reasons why 3- bromo -3- ethyl heptane give no reaction with potassium but bromo-propane

Give a complete stepwise mechanism for the acid-catalyzed hydrolysis of a nitrile to a primary amide.

Give reasons why the compound 3-bromo, 3-ethyl heptane give no reaction with potassium hydroxide but bromo-propane does.

Nitrogen in organic compound is tested by the addition of few drops of saturated iron (iii) sulphate solution to a small portion of sodium fusion filtrate. Dilute hydrogen tetraoxosulphate (vi) is then added to the later solution leading to the formation of prussian blue color or precipitate signalling the presence of nitrogen. Show these steps using equations and name your final product.
