TIFR PYQ Series (Part-1): Organic Spectroscopy

[@bakyabakya4599]

U r certainly a great teacher Sir ❤️anyone can b good in the subject...but being a good teacher is different...tysm Sir 😀

[@cheheksinghal3111]

In last question Answer will be 2,2 - dimethylpropane giving two 13C signals and one 1H signal.

[@shaikhmujeeb3280]

Chemical shift value given in question 2 is quite high for ethyl methyl ketone . Given ppm range are for aromatic compound.

[@sumanamazumdar184]

Yes same thought

[@sumanamazumdar184]

I think nothing of them will be ans

[@pratish96193]

Ans will be 2,2-dimethylpropane...... thank you sir 🤗

[@shashikant2868]

Option C 2,2 dimethyl propane

[@ashwanisingla9196]

That sir but please continue daily

[@AllBoutChemistry]

Will try

[@chemicalreagents1217]

Thank you sir 🙏🙏

Answer c

[@madhavik9934]

In question 2 how ethyl methyl ketone has high chemical shift value?

[@anjaliarya8437]

ya .. 4th option may be correct

[@sandeepprajapati2485]

Yes we can chalange it 👍

[@HimanshuSharma-xn6uc]

Thanks sir

[@aritraguha2715]

Last question answer is c .

[@tanmoydutta5039]

Sir in the question 2 how can we justify the chemical shift values in the range of 7-8 for CH3 and CH2. these values clearly indicate aromatic protons.

[@AllBoutChemistry]

Yes you are correct, there is some problem with the chemical shift values, they're not correct, since any of the option does not carry aromatic proton and question can be done based on splitting and nunber of peaks. But yes the chemical shift values are incorrect.

[@tanmoydutta5039]

@@AllBoutChemistry Okay okay, thank you so much Sir!

[@bidhankumbhakar7771]

@@AllBoutChemistry i think sir , value has given in the tau scale.

[@tanmoydutta5039]

That seems true. Those values do lineup in the Tau scale

[@bhavaniiyer8144]

option c

[@ashaam9496]

Sir how does protons in ethyl methyl ketone give chemical shift values around 7-8 ppm

[@sandeepprajapati2485]

Option C is correct

[@madhukumarrn1905]

Sir please make video on stereochemistry
