Sir , as u solved the two options of enantiomeric pair, I request u to plz solve the other two options of this question also

[@AllBoutChemistry]

Plz check in the comments, I have replied someone regarding this.

[@SahirRayaan]

Plz solve more question with year's question which will help us to understand the concept of the most important topics..

[@AllBoutChemistry]

TAMANNA RAHAMAN,
I usually solve previous years problems alongwith explanation of topic in most of my videos. Plz watch them too... And #SUBSCRIBE for more helpful videos 😊

[@SahirRayaan]

I am telling about the other question ... actually csir net questions solved videos r available in RUclips ....so we r just learning limited example....i hope you understand the actual meaning of my words.... thank you sir

[@AllBoutChemistry]

TAMANNA RAHAMAN,
Now I got what you want to say... Thanks for the valuable suggestion. I'll try to cover extra questions too on the given topic. 👍

[@AllBoutChemistry]

Alright... 👍

[@ershanaoc4264]

Please upload more videos on physical chemistry and inorganic chemistry... Simple topics in organic for csir... It is a request... By doing organic chemistry I hav got negative marks

[@AllBoutChemistry]

I've made many videos on physical and Inorganic and organic scoring topics... Plz watch them... More videos will be uploaded before June.

[@chirrachinna4852]

Thank you very much

[@shubhangikapre3541]

thank you :)

[@BuiXuanHaoKhoaHoaHoc]

In the spiro compound, the absolute configuration is (R); the answer is incorrect.

[@samarjitpattnayak6052]

Sir the compound at 9: 40 is chiral... If u say that's achiral by the Same logic nxt example is also achiral

[@ushabillawaria1505]

sir plz upload more quantum videos

[@AllBoutChemistry]

OK sure 👍

Hi sir i just wanted to prepare seriously for next csir net exam.. Is it possible for me to crack with out coaching... Pls reply sir giv me any suggestions too.. Plzzz

[@Tanishi_Hanvika]

Sir please start Stereochemistry from basic n cover all the topics pf Stereochemistry bcz 50% paper is based on organic which z again depend on Stereochemistry so please clear each n every aspect of Stereochemistry

[@AllBoutChemistry]

i'll try but startring from the very basics is difficult to be finished before coming CSIR exam. but i'll try for sure...

[@Tanishi_Hanvika]

All 'Bout Chemistry sure sirr....u plz try to cover main topics of physical n iNorganic chemistry n spectroscopy... plz share some lecture for thermodynamic n equilibrium solid state for csir levell n other inorganic n physical... u r giving us some Hope dat may b we may clear net through self study n by your guidance

[@AllBoutChemistry]

Thank you for showing your faith in me and my channel, ill be posting videos on physical chemistry topics after completing Group Theory Video Series

[@vanijap6904]

Sir please demroth rearrangement explain

[@zebanashin1655]

Nd also i request you to plzz dont remove offiline option...

[@AllBoutChemistry]

Ok

[@amey56]

Sir in biphenyl you gave example of chlorine and Hydrogen at ortho position. And molecule become achiral . But in that question plane of symmetry was not present because both group on single ring were not same so how molecule became achiral. Please reply need your help.

[@imphenomenal1562]

Okay that's because of the reason that both the groups attached to phenyl ring is not bulky enough to restrict the rotation of the compound.

[@QuantaChemicalEducator]

Thanku sir

[@hr02valesainiankush74]

Then we find R S configuration ???

Sir can you make videos on analogues,alkylidenecycloalkanes and trans cycloalkenes

[@bhawananagar689]

HELLO Sir how to check R rand S configuration in gate2018 question in option no.(A)

[@AllBoutChemistry]

you can see that there is a plane of symmetry in the molecule given in option A which will make it achiral, so we cannot assign R/S nomenclature to them.

Thankyouuuu

Sir please upload the vedio on stereochemistry of nitrogen, phosphorous, and sulphur compounds..

Khan munima, no there is no centre of Symmetry there. The carbon atom at the junction has tetrahedral arrangement and there is no Ci in tetrahedral arrangement.
