Questions & Step-by-Step Solutions
Which of the following is a branched-chain alkane?
Step 1: Understand what a branched-chain alkane is. A branched-chain alkane is a type of hydrocarbon that has a main chain of carbon atoms with one or more branches off of it.
Step 2: Identify the main chain of carbon atoms in the given options. Look for the longest continuous chain of carbon atoms.
Step 3: Check if there are any branches (additional carbon atoms) attached to the main chain. If there are, it is a branched-chain alkane.
Step 4: Compare the options. If you find an option with branches, that is the branched-chain alkane.
Step 5: Confirm that 2-Methylbutane has a main chain of 4 carbon atoms (butane) with one branch (the methyl group) attached to it, making it a branched-chain alkane.
