Question

Natalite is:
A) Ether + petrol
B) Alcohol + petrol
C) Alcohol + ether
D) Alcohol + $KI + {I_2}$

Answer 1

Natalite is used as a motor fuel for internal combustion engines in South Africa. It was introduced during the war because of the impossibility of obtaining petrol and it is very cheaper than petrol.

Complete answer:
Alcohol cannot be used with the maximum efficiency by itself in motor engines because it requires a higher degree of compression than the other engines. So, alcohol of the strength is usually employed as a liquid fuel (95% by volume) will mix with the ether in all proportions. The mixture of ether and alcohol is used as motor fuel and this is called as natalite.
Motor fuel is used to provide energy or power to the automobiles. Natalite is an alcoholic mixture of ethanol and diethyl ether that can be used as a substitute for petrol. Alcohol will not form a stable mixture with petrol or benzoyl under the condition of temperature but increased miscibility at the low temperature and this can be obtained by the addition of third compounds and higher alcohols like amyl alcohol or butyl alcohol.

Thus, the correct answer is option C. i.e., alcohol + ether.

Note: In Natal, a motor fuel that is used for internal combustion engines is composed of 55 parts of alcohol and 45 parts of ether and is known as natalite. It is manufactured from the molasses and from the maize. The production of the natalite is taken in countries like South Africa and England.
