Q: Which of the following compounds is a branched alkane? (2022)
Solution: C5H12 can exist as both straight-chain (pentane) and branched (isopentane) forms.
Steps: 6
Step 1: Understand what an alkane is. Alkanes are hydrocarbons that only have single bonds between carbon atoms.
Step 2: Know that alkanes can be straight-chain or branched. A straight-chain alkane has all carbon atoms connected in a line, while a branched alkane has one or more branches off the main chain.
Step 3: Look at the formula C5H12. This means there are 5 carbon atoms and 12 hydrogen atoms.
Step 4: Identify the straight-chain form of C5H12, which is called pentane. It has all 5 carbon atoms in a straight line.
Step 5: Identify the branched form of C5H12, which is called isopentane. It has a branch in the carbon chain.
Step 6: Conclude that C5H12 can exist in both straight-chain (pentane) and branched (isopentane) forms.
