IUPAC Nomenclature of Alkenes and Alkynes

More IUPAC nomenclature! Now let's look at molecules with carbon-carbon double and triple bonds. We will look at alkynes of alkenes. Get it?

The founding fathers of organic chemistry are really proud of you
You're the only one that doesn't overcomplicate the principles of science
You explain it the way it's supposed to be explained

[yashovardhandubey]

I remember spending 3 years in a tutorial class and not understanding But your lectures actually made science easy.... And life easy.... Thanks a lot

[karefaisesay]

Why is it that the school(s) professors are making chemistry difficult and confusing? You are the kind of chemistry prof we want in the colleges/universities, you make concepts so clear to understand for even a first time learner. They let us think like our heads are upside down...Thnx and God bless u

[jumeepark]

Oh series of videos are extremely helpful... thank you so much for those videos. Your explanation is just super clear and I now start to love o-chem because of your videos. Thank you Professor. Dave!!!!

[la-vida-bellalcaraz]

YOU ARE SAVING MY LIFE RIGHT NOW. My professor just taught me this and I understood nothing. You explained in minutes and its so clear now. THANK YOU!

Just a note for those watching that in recent years, that "Preferred IUPAC Name" (PIN) has changed some of the IUPAC naming conventions to further limit ambiguity about how the molecules are named.
For example, 1-pentanol is now pentan-1-ol. Similarly, 3-penten-1-ol would be called pent-3-en-1-ol.

I just want to say thank you for all your videos. With your help, I was able to not only pass organic chemistry but also get an ‘A’ in it.

[djm.]

Thank you sir for making these great Videos. I learn a lot even though im not a native english speaker. =)

The 28 dislikes are teachers who lost their jobs after students started watching Professor Dave instead of attending their classes .

[kaboom]

Best teacher ever, never knew some one could teach this well . Thanks man, god bless you . Keep up the good work .

[hnrasouli]

With these videos, I could understand organic chemistry easily and engage interestingly in my natural products projects. Dave! You made life live. You're the one thst should win the nobel prize for education.

[Sleepiful]

Enjoying the videos so far.
I was confused what happens if the double or triple bond is not on the longest chain. As far as I understand from a quick search, it's the longest chain containing the double or triple bond which is used for numbering.

[kevinkaria]

4:43 Professor Dave I think that the higher priority would be given to a double bond rather than a triple bond while naming a compound with a double bond and a triple bond at the same position from either side. Please solve my ambiguity! Also your teaching style is awesome and far better than the IIT JEE tutions here in India!

prof dave single handedly helping my grades in science

[germangerman]

You dont know but you really helped me a lot.
THANK YOU SO MUCH PROF.

[mosaedhakami]

Saying thank you is not enough for such a great teacher like yourself .thanks a lot.

[pavankumarjinde]

Thank you for making me understand organic chemistry

[legusurting]

Thank you, Professor Dave, thanks to you I can learn Alkynes of useful stuff.

[briakinard]

you are an amazing teacher! I'm taking organic chem in 12th grade rn.. thank you so much
