Chemistry Multiple Choice

We have nine carbons versus one, two, three, four, five carbons. We know that even though the molar mass here is the same, the length of the chain is actually related to the London dispersion forces.

So if we just look at the pictures here of the structures, this is also true.

In nonane we have these one, two, three, four, five, six, seven, eight, nine carbons.

So we can see that TFP does have these carbon-fluorine bonds, and we know that a carbon-hydrogen bond isn't all that polar, and fluorine is pretty electronegative, so this is true. So this is true, but does it explain the boiling point trend? So we're saying that if the carbon-fluorine bond is more polar than these bonds here, we're saying that if TFP has more polar bonds, that would normally suggest it has stronger intermolecular forces, which would mean you would predict it to have a higher boiling point.

And so, that's the opposite of what we're actually seeing here.

We know it has a higher boiling point, so this also doesn't explain, that doesn't explain the boiling points.

Fundamentals of chemistry multiple choice questions (MCQs), fundamentals of chemistry quiz answers, test prep 1 to learn online secondary school courses for chemistry degree.When something boils, you're not actually breaking any of the covalent bonds, so that doesn't explain anything about the boiling point.Answer choice B says that the carbon-fluorine bond is more polar than the carbon-hydrogen bond.If you are searching where can I get general science gk questions on Chemistry with answers for competitive exams, interviews and entrance test, then this is where we provide you with free online mcq tests for practice and preparation on chemistry GK.Practicing these General Science Chemistry GK question papers in online quiz mode will help you to improve your performance in actual Tests in any competitive exams like - rail, bank, ssc, psc, upsc, tet, etc.If the carbon chains are further apart in nonane, further apart would mean, the further apart they are, the weaker the intermolecular forces.So this would mean, nonane has weaker intermolecular forces, and that would suggest it would have a lower boiling point. And again, this is not what we're trying to explain.So, we're saying, okay, this has a longer chain.Therefore, it will have more London dispersion forces because these molecules are better able to interact with each other with their instantaneous dipoles, and that means these forces go up and the boiling point should go up, and that's what we're trying to explain.So we can see that nonane has a boiling point of 151, versus 89 Celsius for our TFP.Which of the following statements best helps explain this observation?
