Question

which of the following represents c4h10?

Explanation:

Step1: Recall butane structure

$C_4H_{10}$ is butane which has 4 carbon - atoms and 10 hydrogen - atoms. It has two isomers: n - butane (a straight - chain structure) and isobutane (a branched - chain structure).

Step2: Analyze options

Count the number of carbon and hydrogen atoms in each option. Option A has 4 carbon atoms and 10 hydrogen atoms in a straight - chain structure which is n - butane. Option B has 3 carbon atoms and 8 hydrogen atoms. Option C has 4 carbon atoms but the connectivity and number of hydrogen atoms are not correct for $C_4H_{10}$. Option D has 5 carbon atoms and 12 hydrogen atoms.

Answer:

A.
