CPropane
DEthane
Answer & Solution
Correct answer: A. Methane
1. The molecular formula CH₄ contains one carbon atom bonded to four hydrogen atoms.
2. A one-carbon parent uses the root meth-. This saturated molecule has only single bonds, so the alkane suffix is -ane.
3. Combining the root and suffix gives methane, option A. Ethane, propane and butane contain two, three and four carbon atoms respectively.
