Question

EXPLAIN WHY?

(a)Saturated Hydrocarbon are unreactive.

(b)Saturated Hydrocarbon generally burn in air with blue and non sooty flame.

(c)Unsaturated hydrocarbon do not give subsitution reaction.

(d) Saturated hydrocarbon do not give Addition reaction.

(e) Saturated vegetable oil contain fatty acids are harmful for us while Unsaturated vegetable oil contain fatty acid are good for health

Answer 1

Saturated hydrocarbon have only sigma bonds, which are very stable and difficult to break and hence these are unreactive.

In saturated hydrocarbons (alkanes), the percentage of carbon is lower which gets easily oxidised in oxygen of the air to form CO2  completely hence do not produce sooty flame.

Unsaturated hydrocarbons contain double and triple bonds that make reactive for the addition reaction mainly. They do not undergo substitution reaction. Saturated hydrocarbons undergo substitution reaction

Saturated hydrocarbons do contain double and triple bonds that make molecule reactive for the addition reaction and hence these do not undergo addition reaction. They do not undergo substitution reaction.

Answer 2

Answer:

Explanation:because saturated become solid at room temperature while unsaturated become liquid at room temperature
