• A. Meth-
• B. Eth-
• C. Prop-
• D. But-

Answer 1

The correct option is C Prop-

The IUPAC has put forward rules for naming of hydrocarbons. The word roots are selected based on the number of carbon atoms in the hydrocarbon. The root word for a hydrocarbon with 3-carbon atoms is "prop". So, if an alkane had three carbon atoms it will be called propane. The root word for a hydrocarbon with 1-carbon atoms is "meth".The root word for a hydrocarbon with 2-carbon atoms is "eth". The root word for a hydrocarbon with 4-carbon atoms is "but".
