Final answer:
To draw the structural formula for 2-cyclopentylheptane, start with a heptane chain, attach a cyclopentyl group to the second carbon, and add hydrogen atoms to satisfy the tetravalency of carbon atoms.
Step-by-step explanation:
The student's question is asking for the structural formula for 2-cyclopentylheptane.
To start, we identify the parent chain, which is heptane, a seven-carbon saturated hydrocarbon. Next, we look for the substituent, which is a cyclopentyl group, a five-carbon ring. According to the name, this substituent is attached to the second carbon of the heptane chain.
Here are the step-by-step instructions to draw this:
- Draw the seven-carbon chain (heptane) as a straight line of seven carbon atoms connected by single bonds.
- At the second carbon atom of the heptane chain, draw a pentagon to represent the cyclopentyl group. Each corner of the pentagon represents a carbon atom.
- Add hydrogen atoms to each carbon atom so that each carbon has four bonds (hydrocarbons follow the tetravalent rule).
Following these steps will give you the structural formula for 2-cyclopentylheptane. Remember that hydrogen atoms are often omitted from structural drawings for clarity, but ensure each carbon makes four bonds.
