Hi Professor Eman, I had a question about what you said around 16:17 regarding the boiling point of alcohol vs ketones. Does this mean that the boiling points of alcohol are higher than ketones and aldehydes? Or just on a relative scale the increase of boiling point from carbon-oxygen double bond is less then hydrogen bonding but overall ketones and aldehydes are still higher. Thank you for the videos!
Alcohols generally have higher boiling points than ketones and aldehydes due to the presence of hydrogen bonding. The hydroxyl group (-OH) in alcohols forms strong intermolecular hydrogen bonds, which require more energy (higher temperature) to break during the transition from liquid to gas. In contrast, ketones and aldehydes have carbonyl groups (C=O) that engage in dipole-dipole interactions, which are weaker than hydrogen bonds. Therefore, alcohols typically have higher boiling points compared to ketones and aldehydes, even though the carbon-oxygen double bond in ketones and aldehydes also contributes to increased boiling points compared to hydrocarbons without these polar groups. Hope that helps!
Hi Professor. With cyclopentane carbaldehyde @ 8:02, could you add a note/edit to include the hydrogen on the terminal carbon? Anyway, love your videos; they are very helpful and the best I've found as a companion to the Kaplan books. Thank you so much. ❤
Hi Professor eman, when do you think you will be done with this series? I will be taking my exam in jan, and I have used your organic playlist as my source of notes. Do you think you will have it before?
Hi Sorry to bother! I was just wondering when you plan to have the rest of the organic chemistry lectures up? No rush, just trying to plan out my studying! @@professoreman2289
Per usual leaving my daily comment to support!

Of course, sorry for missing that there!
swear if I had you as a professor I would've had so much fun with orgo
You are so sweet! Thank you🥹❤️

Hi! I definitely think it will be done before Jan! I am aiming for it being done near the end of November!:)good luck!
Another great video!

HI! Would you be to upload your notes for this chapter on the google drive? I just see the notes for the problems.
Terribly sorry for the delay! I will have them up tonight:)
No worries! Your help is amazing! @@professoreman2289

hello professor, the notes you uploaded only have the first page :( are you able to upload all the notes? please and thank you!
hi! so sorry for the delay, they should be up now:)
@@professoreman2289 thank you so much! I'm very grateful for all of your videos. they have been amazing
Great Video thank you!
Thank you for watching!!
