Thank you for the knowledges, I'm sure it will helps me a lot on my final exam next week.

[@Leah4sci]

You're welcome. Always glad to help! I hope your exam went well.

[@notzuhriashraaf4912]

@@Leah4sci just got my result, I got an A for my organics😁 thank you for teaching. But did not get an A for inorganics. But I will work harder.

[@Philophiler]

My exam is also next week

Watching your videos made me able to learn the information 10x faster rather than studying for days and would have so many questions on different problems. Amazing explanation and so much easier to learn from watching your videos! They're incredibly helpful!

[@Leah4sci]

I'm so glad to hear this! Thanks for watching.

[@jennie1316]

YOUR OCHEM VIDEOS ARE BEYOND HELPFUL!! Thank you!! I love how in depth you go and the pace you explain it is perfect!! Color coding, examples, and concept explaining are helping me so much with ochem!!

oh wow! Thank you! :)

[@akinn1864]

This was rly helpful! I'm currently doing all of this but in German, so videos like this rly help my understanding! I've been confused a lot cuz I don't understand German that well but this video made me unconfused(ik it's not a word). You have my sincere gratitude. Thank you!!!

[@Leah4sci]

lol, unconfused sounds like the best explanation to me, and I'm happy to unconfuse you!

[@akshansh3412]

Thank you, mam! Followed you for almost 1 year and i can't speak much about the improvement in organic chemistry. Mam, one more help is needed on chapter AMINES!

At 2:12 The partial charge on hydrogen should have positive charge and that on oxygen should have partial negative charge..... Its a correction... 😊😊

Oh shoot! You’re absolutely correct. Thanks for catching that. Alas KZbin does not allow for editing published videos though

[@svnspell6709]

Hey! In my book its written phenol has stronger hydrogen bonding compared to alcohol,can you explain it how? Wouldnot be it all stacked up and occupy do much space and disturbs the bonding ? is due to

[@Leah4sci]

Since phenol allows the oxygen to resonate its electrons into the benzene ring, the negativity is pulled down and away from the hydrogen more than just on a regular alcohol. If the H is left more exposed and more partially positive, it will have stronger H-bonding as a result

[@svnspell6709]

[@nainanikks6144]

Hi mam...I have a doubt ...that if I compared 3 ° alcohol ,2° alcohol ,1° alcohol in order of solubility ....what should be the order???? Please answer my question mam😞😞

[@Leah4sci]

It ultimately depends on the specific molecules, their sizes, and the presence of any other polar groups. Unfortunately, I don't offer tutoring over social media.

Which compound shows maximum hydrogen bonding with water? Ethanol or methanol. With reason mam

Both can create one hydrogen bond with a water molecule. Since I don't offer tutoring over social media, for help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/

Which compound have strongest hydrogen bond between ethanol and ethanoic acid?

[@Leah4sci]

This question is not explicitly covered in this video. However, I can say that ethanoic acid has stronger forces of intermolecular attraction because, through resonance, it has the potential to form hydrogen bonds at two points within the molecule.

may i ask about, what is the yellow bond that u draw between the alcohol molecule?(when u explain the bp between primary,secondary and tertiary alcohol)

[@ryu.l2264]

or it just means "holding to each other"?

@@ryu.l2264 It is the intermolecular forces between the carbon chains due to london-dispersion forces (temporary dipoles in non-polar bonds)
