What is 2-methylpropane called?
Isobutane
Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC(CH3)3. It is an isomer of butane. Isobutane is a colourless, odourless gas. It is the simplest alkane with a tertiary carbon atom.
What is 2-methylpropane used for?
2-methylpropane is used in the production of alkylate petrol and isobutylene as well as in the manufacture of pharmaceutical and cosmetic products. Due to the ozone-diminishing effects of freons, this substance is gradually replacing them in aerosols and as coolants in refrigerators.
What is the structure of 2-methylpropane?
C4H10Isobutane / Formula
What does the 2 mean in 2-methylpropane?
A methyl group has one carbon, and looks like this: So methyl butane is butane with a methyl group attached. The 2- tells you where that methyl group is attached: on the second carbon: The thing is, that 2- is not strictly necessary.
Why is methylpropane called methylpropane?
When you follow the IUPAC naming rules, the longest continuous carbon chain consists of three carbons (propane) and you are left with one carbon (a methyl group) bonded to the second carbon in the chain (that’s what the 2 means). That gives you 2-methylpropane.
What is the molar mass of 2-methylpropane?
58.12 g/molIsobutane / Molar mass

What is the difference between butane and 2-methylpropane?
Butane boils at -0.5 degrees Celsius, while 2-methylpropane boils at a lower temperature of -11.6 degrees. The 2-methylpropane molecules can be viewed as spherically shaped, like a ball, while the butane molecules look more like a hot dog.
Is bromo 2 secondary Methylpropane?
Explanation: There are four isomeric haloalkanes with molecular formula C4H9Br . The primary bromides are 1-bromobutane, CH3CH2CH2CH2Br , and 1-bromo-2-methylpropane, (CH3)2CHCH2Br . The secondary bromide is 2-bromobutane, CH3CH2CHBrCH3 .
Is 1-Bromo-2-Methylpropane optically active?
On the other hand, 1-Bromopentane and 2-Bromo-2-methylbutane do not contain asymmetric carbon, hence they are not optically active.
