Example: Choose the name for CH3CH2CH2CH3
The answer of the last question will be shown here with an explanation.
The longest chain or parent chain has 4 carbon atoms (prefix: 'but'), since there are no substituents (groups appending from the parent chain) and it is not cyclic (or a ring) it is an alkane (suffix: 'ane') and therefore called butane. -- The explanation can assist you in understanding the question and answer.
