Woodward-Fieser's rules for Enones

[@aaa-uz2ro]

shouldn't we add another 5nm for the last example because there is an exocyclic double bond

[@sadiaaleem95]

Yes

[@SavarahMarian]

No the double bond is not exocyclic since it is a diene

[@jameschem]

Thanks alot. But the last example, please why didn’t we add the edo yip pic double bond.

[@keziahdamoa6923]

Thank you, your lessons are very detailed and helpful .

[@ChemWis]

You are welcome!

[@avantikaverma3949]

Last wale example me ek exocyclic bond hain sir

[@deyao]

‏‪11:54‬‏ when we should've calculate the homoannular diene component(39) to find lambda max value?
Thanks❤

[@Trendsofchallenges]

Sir for the last example
Why didn’t you add the exocyclic when calculating?

[@sumaviaaftab5125]

Sir last example mn exocyclic double bond add kun ni kiya plz reason day dain

[@ChemWis]

Watch it carefully again, you will understand

[@sumaviaaftab5125]

We will consider only that exocyclic double bond which is included in conjugation?

[@ChemWis]

Right

[@Ahmad462]

How is the last example homoannular ?

[@Ifodei]

In the same cyclic enone

[@nusratmumu5264]

There is no exocyclic in last example

[@charulatha7408]

I have a doubt sir. When you are explaining about the first example of cross conjugated dienes at 10.20 minutes , you are adding base value 215nm with 2 beta ring residue 24nm and one exocyclic 5nm and total is 244nm. In this example why we are not taking Homo annular diene value?

[@priscillablessed9057]

The homoanular diene you are looking at is not part of the alpha beta conjugated system we are considering. He said we would have to consider the alkene with the highest number of ring residues. So the alkene to the right was considered as the conjugated system. The alkene on the left wasn't considered because the alkene on the right has the highest number of ring residues.

[@shreyadixit9999]

That is not in conjugation

[@raphaelprecious7173]

wow this is amazing thank you very much

[@CreativeRishu121]

For aldehyde, base value is 207. Not 210

[@ayeshadeshmukh5018]

Thank u so much sir .Its very helpfull for us🙏🙏😊

[@MR.Minimiltia]

Thank you very very much❤️❤️

[@cutesherni3433]

How to find a lambda max for a same molecule that have a pi bond different position
Ex ., CH2=CH-O-CH3 & CH3-O-CH=CH2

[@mudassarali4235]

Thank you but last example is not homoannular diene😊

[@deepsearching583]

Why it's not homoannular ?

[@chembeautoxy1896]

Sir plz do a video for retrosynthesis
It will be very helpful
Plz sir

[@ChemWis]

Okay sure

[@skyscrapers3866]

Yes sir, plz make videos on retro synthesis.. your explanation are so awesome and you teaching style so nice .. we can easily understand...

[@chembeautoxy1896]

@@ChemWis thank u Sir........ Actually the retrosynthesis make me in trouble that's y sir ........

[@Dr_Arman796]

Sir last example is not homoannular

[@amanadleshorts7429]

Nice explanation

[@GarimaMall12]

Thank you sir
