What is the IUPAC name of the hydrocarbon with the structural formula ?
Answer and explanation
Correct answer: A. Butane
- Step 1: Count the continuous unbranched chain of carbon atoms: there are 4 carbon atoms connected by single bonds.
- Step 2: The prefix for 4 carbons is 'but-', and single-bonded saturated alkanes take the suffix '-ane', giving butane.
Answer
Butane.
Why not the others: 'Propane' is a 3-carbon alkane; 'Pentane' is a 5-carbon alkane; 'Ethane' is a 2-carbon alkane.
