Sir in problem 4 hum direct distribution ration nhi find Kar sakte mole se
@@DrNamdeoTDhokale sir jo intial concentration aqueous layer me hota hai whi total hota hai?? To mole diya hai usey volume of aqueous layer se divide karke nhi nikal sakte sir ??
@@anshikashrivastava5703 yes you are right 👍 We can calculate as Conc. Of organic layer= 0.019/60= 0.0003166 Conc. Of aqueous layer= 0.001/80= 0.0000125 Distribution ratio (D)= total conc of solute in org layer/total conc of solute in aq layer D = 0.0003166/0.0000125 D = 25.28 Answer will be same

nice sir
sir Erythronolide A related any information?
Tq for everything sir
Outstanding job....sir
Thank u sir acid basis full chapter
Thank you sir
Problem s on volumetric solution
Bohot accha explain kiyee ho sir ✨
Is 51 option corct?
Yes because for more polar compounds partition is more suitable
Khup 👌sir teaching
5th question is wrong... Standard calomel electrod use hota h as a reference electrode
It is all about polarography So question is correct and answer is also correct 👍

Thank you sir, this all video help me a lot for my university exam purpose.
Sir 4th question ka b option nhi hoga ???
4th question ka option a) change in weight
b option for DTA
Thank you very useful questions 🙏
Answer of Question no 28 is B not A
No as concentration increase Absorbance increase and transmittance decrease
Thank you sir, my doubt is cleared.😊
Very helpful...thank you🙏

Excellent...sir...only helpful video on 1 6 disconnections...
3rd example main cheating ki hai aap ny
How?
3rd position py substitution lgani thi aap ny 4th position py lgai
Or synthesis main different synthetic equivalents use kiye
@@2355open substitution 4 no pe hi hai you can observe carefully only mistake in double bond. There should be double bond between 3-4 and 1-6. That mistake i had made
Ok and by the way this video was very helpful for us thank you so much
