Q
Q: Which of the following is a branched alkane?
Solution: Isopentane is a branched alkane, while the others are straight-chain alkanes.
Steps: 6
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. Straight-chain alkanes have all carbon atoms connected in a single line, while branched alkanes have one or more carbon atoms connected to the main chain, creating branches.
Step 3: Identify the options given in the question. Look for the names of the alkanes provided.
Step 4: Analyze each option. Determine if the structure of each alkane is straight or branched.
Step 5: Recognize that isopentane has a branch in its structure, making it a branched alkane.
Step 6: Conclude that isopentane is the correct answer, while the other options are straight-chain alkanes.
