2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH3)3CCH2CH(CH3)2.
How do you name isooctane?
Quantity. Isooctane (or Iso-Octane), also widely known by its IUPAC name 2,2,4-Trimethylpentane, C8H18, CAS 540-84-1, is an organic hydrocarbon alkane and an isomeric form of octane. Structurally, it consists of pentane with two methyl groups at position 2, and a single methyl group at position 4.
What is isooctane in organic chemistry?
Isooctane is an alkane that consists of pentane bearing two methyl substituents at position 2 and a single methyl substituent at position 4. It has a role as a fuel additive, a non-polar solvent and a nephrotoxin. It is an alkane and a volatile organic compound.
What is the structure of isooctane?

2,2,4-Trimethylpentane/Formula
What does isooctane mean?
octane
Definition of isooctane : an octane of branched-chain structure or a mixture of such octanes especially : a flammable liquid octane used in determining the octane number of fuels.
Why is isooctane a misnomer?
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.
Where is isooctane found?
petroleum industry
Isooctane is produced on a massive scale in the petroleum industry by alkylation of isobutene with isobutane. The process is conducted in alkylation units in the presence of acid catalysts.
How do you write tert-butyl in Iupac?
According to Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names 2013 (Blue Book) (P-57.1. 2), the preferred prefix for −C(CH3)3 is “tert-butyl”.
What is butyl in chemistry?
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C4H9, derived from either of the two isomers (n-butane and isobutane) of butane.
Why does isooctane have different structure?
Like octane, isooctane has eight carbon atoms and is also used as a fuel. Isooctane is an example of a branched chain hydrocarbon, and is a five carbon chain with three methyl groups at various points in the chain. Both ocatane and isooctane are isomers – they have the same molecular formula but different structures.
Is ISO used in Iupac?
‘iso’ and ‘neo’ are used in common name system. They won’t be used in IUPAC nomenclature.
