Explanation:
Definition: Hydrocarbons are organic compounds containing only carbon and hydrogen atoms. They can be classified as alkanes, alkenes, or alkynes based on the type of carbon-carbon bond present in their structure.
Molar Mass: The molar mass of a compound is the mass of one mole of that substance. It is calculated by adding the atomic masses of all the atoms present in the molecule.
Identification of Hydrocarbon: The given hydrocarbon has a molar mass of 100 g and contains 4 methyl groups. This means that it has a molecular formula of CnH2n+2, where n is the number of carbon atoms in the main chain.
Calculating n: The molar mass of the 4 methyl groups is 15.96 g (4 x 3.99 g), which means that the main chain has a molar mass of 84.04 g. Dividing this by the molar mass of one carbon atom (12 g/mol) gives us 7.003, which we can round off to 7. This means that the main chain has 7 carbon atoms.
Identifying the Structure: The hydrocarbon has a quaternary carbon atom, which means that it is bonded to four other carbon atoms. The only possible structure with 7 carbon atoms and a quaternary carbon atom is 2,2-dimethyl pentane.
Conclusion: Therefore, the identity of the given hydrocarbon is 2,2-dimethyl pentane.
