Question

is this an aromatic hydrocarbon? why or why not? yes, because the carbon chain is made up of single bonds yes, because the carbon chain is ring shaped no, because the carbon chain is composed of only a single ring no, because the carbon chain has no double bonds

Explanation:

Aromatic hydrocarbons have a planar, cyclic structure with alternating single and double bonds (conjugated system) and follow Hückel's rule (4n + 2 π - electrons, where n is an integer). The given hexagon - shaped carbon - chain has no double bonds, so it is not an aromatic hydrocarbon.

Answer:

No, because the carbon chain has no double bonds
