Write condensed structural formulas f name for the following molecules 1. CH CH,-CH-CHz-CH2-CH2-CH,-CH2-CH
The Correct Answer and Explanation is :
The given molecule is:
CH₃CH₂-CH₂-CH₂-CH₂-CH₂-CH₂-CH₃
This is a straight-chain alkane with 8 carbon atoms. The condensed structural formula for this molecule is:
C₈H₁₈
The molecule is octane, which is a simple alkane (saturated hydrocarbon). Its molecular structure is straight-chain with no branches.
Explanation:
- Alkanes: These are hydrocarbons that consist of only single bonds between carbon atoms. The general formula for alkanes is CₙH₂ₙ₊₂, where “n” is the number of carbon atoms. In this case, with 8 carbon atoms, the formula fits the general form of alkanes.
- Condensed Structural Formula: This type of formula simplifies the drawing of molecules by showing the carbon backbone and hydrogen atoms attached to each carbon atom. In the condensed structural formula for octane, the hydrogens are implied based on the number of bonds each carbon needs to satisfy its valency of 4.
- Structure: The structure consists of 8 carbon atoms in a straight line with hydrogen atoms filling the remaining bonds to ensure each carbon atom achieves its maximum of four bonds (as per carbon’s tetravalency). This formula assumes that each carbon atom is bonded to the necessary number of hydrogen atoms to make a stable molecule.
- Chemical Name: The molecule is named octane because it contains 8 carbon atoms. The prefix “oct-” indicates 8 carbon atoms, and the suffix “-ane” denotes an alkane.

I will now generate an image that represents the structure of octane.
Here is the structural diagram of octane (C₈H₁₈), showing the straight-chain alkane with 8 carbon atoms and the appropriate number of hydrogen atoms attached to satisfy carbon’s tetravalency. Let me know if you need further clarification!
