Answer:
The correct option is;
A. Branched chain alkanes
Explanation:
By the process of cracking of petroleum, higher quality petrol are formed by converting straight chain petrol to branched petrol, which are the grade of petrol that burns more smoothly and therefore efficiently within internal combustion engines
The cracking process includes;
a) The conversion of alkanes which are large molecules into branched octanes
b) The conversion of alkanes with straight chain into branched chain alkanes
c) The formation of a branched chain alkane and an alkene from straight chain alkanes
d) The formation of branched chain alkane and hydrogen gas from a straight chain alkane.
Answer:
A pure substance consists only of one element or one compound and a mixture consists of two or more different substances, not chemically joined together.
