which alkane is the isomer of butane called 2-methylpropane
Isobutane Isobutane, also known as i-butane or methylpropane, is a chemical compound with molecular formula C 4H 10 and is an isomer of butane. It is the simplest alkane with a tertiary carbon. Isobutane is used as a feedstock in the petrochemical industry, for example in the synthesis of isooctane.[5]
Bunsen burner The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both.
Refrigerant In order from the highest to the lowest potential of ozone depletion are: Bromochlorofluorocarbon, CFC then HCFC.
Isoelectric point For an amino acid with only one amine and one carboxyl group, the pI can be calculated from the mean of the pKas of this molecule.[4]
