2, 2, 4-trimethyl pentane
iso-octane i.e. 2,2,4-trimethyl pentane has highest octane number.
n - hexane X−→ 2 - methyl pentane+ 3 - methyl pentane. The name of the reaction and 'x' is
ASSERTION: n-Pentane and n-Hexane belong to a homologous series.
REASON: n-Pentane and n-Hexane belong to the same class of hydrocarbons and they differ by a - CH2 - group.
