Thank you so much.

[@epiphany6481]

Thanks to your video, I now know exactly what an exocyclic double bond is. Thank you so much!!!

[@labileeducation927]

You are so welcome!

[@mudrapandya5671]

Last example is wrongly calculated .

[@muhammadyusrilbaihaqi8350]

Exactly

[@labileeducation927]

No, It is correct. It is the example of cross conjugation.

[@sliceline1015]

Homoanular was supposed to be 253nm

Me: frustrating by leaurning for an exam
this Hero 2 Years ago: Hold my beer

[@mimkhatun9978]

In the example of exocyclic double bond, 4th and 5th both are heteroannular, then why one have 1 exocyclic double bond and other have 2?

[@labileeducation927]

In the initial part of the video, identification of exocyclic double bond is clearly explained.

[@nwukorvera5085]

Your exocyclic double bond for the last question is incomplete.

[@MR-bb9gu]

How?. I guess he calculated exact.. bcz in last structure, only double bond of RING-C is exocyclic to ring B, all other bonds are endocyclic

[@labileeducation927]

No, It is complete.

[@labileeducation927]

Thank you

[@BRODYy23]

Agreat video thank you so much 🌹😻😻FROM IRAQ
LOVE TO YOU 🌹❤️‍🔥

[@ClemensEssonAppiah]

hi but pertaining your last question why is is that you chose only one double bond extending conjugation

[@あかし中村]

What's the Absorption maxima?
How can I calculate that?
You just tell about Lambda Maxima....
What's the Absorption Maxima?
Help please help

[@Lamar.Lamar239]

For the fifth example it's 5×5 not 5×4

[@labileeducation927]

Yes, you are right. I have already corrected in the same video.

[@antonoracha51]

Thanks

[@labileeducation927]

Welcome

[@mohananjula8043]

5th one answer is 343

[@labileeducation927]

No, answer is 313 nm. we will not consider extreme left double bond due to cross conjugation.

[@estherngao]

i tend to defer with your last example computation, there's no double bond extending conjugation

[@labileeducation927]

We take base value for the diene system. any extra double bond is considered as the double bond extending conjugation.

[@habibanaqash9749]

Good

[@labileeducation927]

Thank you

[@nikhleshvarma5522]

Sir aape acrylic ka man Galt rkha he

[@labileeducation927]

No, ye sahi hai. kuchh books me 1 or 2-3 nm ka difference mil sakta hai.

[@Fateh_Ali_17]

Last is wrong

[@cutecat3087]

acyclic system has 217 nm value.
