Question

Consider the table of boiling points and structural isomers. These are the boiling points for the unbranched hydrocarbons listed. Consider your models and, drawing on your knowledge of bonding and chemical forces, infer what might contribute to the increasing boiling points as the carbon chains grow longer. Then state whether you think all of the isomers of a compound have the same or different boiling points; give a reason for your answer.

Answer 1

The isomers of the compound do not have the same boiling points

Step-by-step explanation

Isomerism is defined as the phenomenon in which one compound has the same chemical formula and different structural formula.

The table provided shows the boiling point of alkane compounds.

Recall, that the boiling points of alkanes increases as the molecular size increases (number of carbon atoms)

For isomers of each compound, the boiling point will decrease as the compound has a more branched chain.

So, the more branched chain we have to form the isomer, the more the boiling will decrease

Hence, the isomers of the compound do not have the same boiling points
