What are hydrocarbons? Write the name and general formula of
saturated hydrocarbons
unstaturated hydrocarbons and draw the structure of one hydrocarbon of each type. How can an unsaturated hydrocarbon be made saturated?

What do you mean by unsaturated hydrocarbons?

What do you mean by saturated hydrocarbons?

An organic compound C_8H_18 on monochlorination gives a single monochloride. Write the structure of the hydrocarbon.

Urea (H_(2)NCONH_(2)) is manufactured by passing CO_(2) (g) through ammonia solution followed by crystallization. For the above reaction is prepared by combustion of hydrocarbons. If combustion of 236 kg of a saturated hydrocarbon (C_(n)H_(2n+2)) produces as much CO_(2) as required for production of 999.6 kg urea then molecular formula of hydrocarbon is:

A dihalogen derivative (A) of a hydrocarbon having two carbon atoms reacts with alcoholic potash and forms another hydrocarbon which gives a red precipitate with ammoniacal solution of cuprous chloride. Compound ‘A' gives an aldehyde when treated with aqueous KOH. Write down the name and formula of the compound.
