CARBON COMPOUNDS PART-5

Chemical Properties of Carbon Compounds:

Combustion

Carbon compounds burn in oxygen to form water, carbon dioxide , heat and light

Oxidation

Carbon compounds like alcohols are oxidized to form carboxylic acid on heating with oxidizing agent like alkaline potassium permanganate or acidic potassium dichromate.

For example -Alcohols are oxidised to carboxylic acid

Addition reaction

Unsaturated hydrocarbon undergo addition reaction with hydrogen in the presence of nickel and palladium as a catalyst to form saturated hydrocarbon.

Hydrogenation of oils:

  • Vegetable oils, like alkenes, undergo hydrogen addition to generate a saturated product called vegetable ghee or vanaspati ghee, which is solid or semi-solid at room temperature. This reaction is known as the hydrogenation of oils.

 

Substitution reaction

Saturated hydrocarbons undergo substation reaction with halogen to form substitution products

Methane reacts with chlorine in the presence of sunlight and form substituted products
