I believe the answer is aldehydes but get a second opinion. Branched gives, I believe, an aldehyde and a ketone.

Sugar oxidizes pretty easily, doesn't it? And ketone not as well? Thank you. Sheryl I think that is right. Alcohols go to aldehydes and they go to ketones.

Are the words in brackets correct? If not, correct it. 1. Aldehydes and ketones are [less] polar than hydrocarbons. I think aldehydes and ketones are polar, so should I change it to "more"? 2. [Hydrocarbons] have stronger intermolecular forces than aldehydes and ketones. I had...

Your answer to #1 is correct and you should change it to "more". If you think about #1, you should know that #2 is false. Think about it. If aldehydes and ketones are more polar molecules than alkanes, then wouldn't aldehydes and ketones have stronger intermolecular forces.

Oxidation of an alcohol will produce two possible products; i.e., an aldehyde or a ketone. The aldehyde is just half way and the ketone is all the way. So which you get depends upon how strong the oxidizing agent is. I think the answer to your question is b.

Chemistry
A ketone is R2C=O; therefore, if we make R1 a CH3 group (the simplest) and the second R group a CH3 group, that makes 3 C atoms. If you take one of the R groups and try to make it smaller (like making it a H atom), one ends up with RCHO and that is an aldehyde, not a ketone.
