select the structure for octane.
select the structure for octane.
Answer
Explanation:
Step1: Recall octane structure
Octane is an alkane with 8 carbon - atoms. Its molecular formula is $C_8H_{18}$ and it has a continuous - chain structure with single bonds between carbon atoms. Each carbon atom forms 4 bonds.
Step2: Analyze options
The first option shows a continuous - chain structure with 8 carbon - atoms connected by single bonds, which is the correct structure for octane. The second option has 6 carbon - atoms and the third option has 5 carbon - atoms.
Answer:
The first structure (the one with 8 carbon - atoms in a continuous zig - zag chain)
