Q
Q: Which of the following alkanes has a branched structure?
Solution: Isobutane is a branched alkane.
Steps: 5
Step 1: Understand what an alkane is. Alkanes are hydrocarbons that consist only of carbon (C) and hydrogen (H) atoms, with single bonds between the carbon atoms.
Step 2: Know the difference between straight-chain and branched alkanes. A straight-chain alkane has all carbon atoms connected in a single line, while a branched alkane has one or more carbon atoms connected to the main chain, creating branches.
Step 3: Identify the alkanes given in the question. Look for the names or structures of the alkanes provided.
Step 4: Determine if any of the alkanes have branches. For example, isobutane has a main chain of three carbon atoms with a branch from the second carbon.
Step 5: Conclude that isobutane is the branched alkane among the options.
