This video shows you the reaction and mechanism for the hydroboration oxidation of alkynes, in which an alkyne reacts with a boron-containing reagent, followed by NaOH and H2O2, to form either an aldehyde or ketone product at the less substituted, anti-Markovnikov position.
You’ll learn the step-by-step alkyne hydroboration oxidation mechanism, including Keto Enol Tautomerization to isomerize an unstable enol intermediate in a basic environment.
Finally you’ll learn about the regioselectivity of the reaction and compare the products when starting with terminal, symmetric or asymmetric internal alkynes.

I want to express my deepest gratitude for the invaluable help your videos provided me with. As a returning student after many years, I found myself struggling to keep up with my organic chemistry course. However, your videos have been a lifesaver, and I am thrilled to report that I just took the final exam and received a 77%. Although I believe that if I had discovered your videos earlier in the semester, I could have earned an A, I am still immensely grateful for your help. Thank you for your dedication and commitment to helping students like me succeed.
Wow, thank you so much for the kind words! I'm always happy to help, and I love to hear these kinds of success stories! Thanks for watching and following my channel :)
at my third year in university, I attended all of your videos and i was so grateful and wanted to thank you in person.
Now I'm running the quality and lab departments at one of egypt's largest chemicals and fertilizers companies.
So, Thank you very much and keep up the tremendous work.
Oh wow that is very cool! I'm honored to have been able to help you in your journey
I am from India and you are very helpful to clear my joint entrence exam (jee).
Thank you so much !
Most welcome!
Did you already take the JEE, and if so, how'd it go?
Same bro
Good job.Simple n lucid explanation in detail
Thanks so much!
You explained it soo well, before this video I was struggling so much to understand thank you so much
You're so welcome, I'm glad it cleared things up for you

thank you!! although Im struggling right and had found you in the middle of the semester, I feel a little confident and assured iI can do well before class ends
I'm so glad you found me when you did! Make sure to check out leah4sci.com/syllabus to match all of my resources and videos with what you are studying.
Thanks helped me a lot in my jee prep
Happy to help!
Congrats for your 200K🔥❤🔥
Thanks so much! :)
@@Leah4sci Yes, definitely congrats!
Amazingly taught
Thank you!
Thank you so much for these videos, they're really helpful for my preparation of NEET exam. Really helps me clear concepts in a very quick and easy way
Glad to help
If you don't mind my asking, how'd your exam go?
@@PunmasterSTP I've got 4 more days for the exam.
@@w.cgaming38 Oh snap, I hope it goes well!
@@PunmasterSTP thanks!
Really in awe of your explanations! :)
Thank you so much! Glad you're finding them helpful
Leah4Sci is kinda goated
Thanks!
Your a life saver!
Can't thank u enough!!
You are so very welcome!
Thank you for this!!
You're so welcome!
Love from India mam
Thanks!
Mam can you please make a video on some important methods of preparing alkanoids please
Thanks for the recommendation. I post free videos as I have time and am always looking for suggestions. For more help with this topic in the meantime, contact me through my website: leah4sci.com/contact
please make video on isomerism
Thanks for the recommendation. I post free videos as I have time and am always looking for suggestions. For more help with this topic in the meantime, contact me through my website: leah4sci.com/contact
In the last compound, which is the major product ; 2 pentanone or 3 pentanone?
It should produce a racemic mixture of both compounds, where neither is considered the major product. In other words, a 50/50 mixture.
where is the practice quiz?
I'm sorry, but the Alkyne Practice Quiz has not been published. I don't have a firm date as to when that will be made available. I create free content as I have time, and this is one of those projects still in the works.
Haha, first to comment.
Anyway, thanks Leah for all these videos, they help us in so many ways.
Woohoo! :)
You're very welcome
Where were you when I was an undergraduate 😂
That depends, when were you in undergrad?
Is this AI voice?
You tell me
hello my friend, can you tell me what is your tools that u are using for these tutorials, because i want to make some lectures for my students in iraq
Let's keep the questions relevant to the video please
@@Leah4sci relax, don't be mad.
@@REDOXorg Yeah I'm with you and I'd be interested too. I also feel like the question you asked *was* still relevant to the video...
@@PunmasterSTP thank you sir, i appreciate your words.
this is her teaching the topic. she probably has done her studies in chem so you can't ask her what materials she is using. the fact she is able to teach us in a concise way means she has learned this stuff to teach us. you can always learn from her, from other videos, and materials to teach as well
