why is 2,2,4-Trimethyl pentane called isooctane?
Answers
Answer:
Explanation:
Chemical and organic isomers are named on the basis of nature of the carbon chain, as in the number of branches in the molecule.
When we talk about the iso-prefix, it is used when all carbon but one form a single chain while the remaining one forms a branch with the main carbon chain.
In isooctane, there are 3 carbon existing as branches and only 5 carbon in the main chain. Hence it does not follow the iso rule.
The IUPAC name for this compound is 2,2,4-trimethylpentane. Again, this chemical is used to determine octane ratings of fuel. Octane rating is a measure of the fuel’s anti-knocking ability. As the name 2,2,4-trimethylpentane is too tedious to pronounce, the name isooctane just stuck on.
