Question

question 9 of 10
which of the following is the correct model of c₈h₁₈?
a.
b.
c.
d.
← previous

Explanation:

Step1: Analyze the formula of octane

$C_8H_{18}$ is octane, an alkane with 8 carbon - atoms. In a line - bond structure of an alkane, each carbon is bonded to other carbons and hydrogens. The carbon - carbon bonds are single bonds. The line - bond structure should have 8 carbon atoms connected in a chain (in the case of a straight - chain octane). Each 'V' shape represents a carbon atom.

Step2: Count carbon atoms in each option

Option A has 5 carbon atoms. Option B has 6 carbon atoms. Option C has 8 carbon atoms. Option D has 7 carbon atoms.

Answer:

C.
