Iso-octane $\rightarrow$ $CH_3-C(CH_3)_2-CH_2-CH(CH_3)-CH_3$

Vedclass · Answer

(D) The structure provided for iso-octane is $2,2,4$-trimethylpentane. While this is the universally accepted common name for this compound in fuel chemistry (octane rating),it does not follow the systematic "iso" prefix rule. The "iso" prefix typically denotes a single methyl branch on the second carbon of an otherwise straight chain,which for an octane would be $2$-methylheptane. Therefore,compared to the other standard common names,this is considered an exception or a mismatch in strict nomenclature terms.
