.
Extra - inversion of sucrose, structural evidence of glucose, DNA and RNA, water soluble and fat soluble vitamins,

[snehaumade]

Quest- 13, 14, 15, 16 to 20 ( define), 22, 31*, 33*, 36*, 41, 43, 44
Above questions are reaping and also are important !

Thanku sir this series is really very helpful thanku so much

sir, the reaction of glucose with HNo3 confirms the presence of primary alcohol in glucose and the the reaction with acetic anhydride confirms the presence of 5 OH group in glucose

[aaradhyapuranik]

Sir I scored 68/70in chemistry in my school pre boards just by watching your pyq series and mcqs given by you thank you sir in half yearly my score is just 50 by your content my 18m increases thanks sir again

Amylose is water soluble whereas Amylopectin is insoluble in water

[opmehrayt]

Thanks alot sir because of you only i got that confidence of 100 marks ab bas is chapter ko or karlu uske baad 9 chapters or h bas or pura syllabus complete abki baar 💯 apni ✊ me 😀

17:20 for primary alcohol detection in glucose, conc hno3 is used which will oxidise ch2oh into carb acid grp, also glucose pentaacetate is formed for the detection of 5 hydroxyl groups, but 4 of them are 2ndry not primary
overall, the video is veryy gudd, helped me a lot

[aritrasur]

Thank you so much sir I took the 10 days pledge I will get 95+ in boards I have completed all PYQs, MCQs, Notes and even gave sample papers your content is truly top notch Thanks again <3

[chetnasharma]

sir Q22 Ka second part m primary alcohol ki presence confirm krni h so hum oxidation with nitric acid krenge na it will give saccharic acid which confirms the presence primary alcohol..kyuki acetic anhydride gives pentaacetate which confirms the presence of 5 -0H groups aur question m primary alcohol poucha hai .

[ommishra]

10, commercial mop of glucose, 6, 14, 17(defination), 18, invert sugar defination!, 22(i), done till 20mins

[Mindsetmonster]

14:41 Amylose is water soluble and Amylopectin is insoluble, Thank you sir for providing us such a good content.

[prince]

I was failed in half yearly
But after watching this series I scored 50 marks in preboard

[Anjali-yvqt]

Sir doubt... Q no. 22 ka (II) ans reaction with HNO3 hoga.... Acetic an hydride ye confirm ka Krta h ki 5 OH group present h naa ki primary alcohol

[strangeproduction]

Sir Q-22 m primary alcohol ki presence ke liye puccha hai na tuo HNO3 se oxidation krana chaiye na (16:14)

[editing.edition]

Who is watching today for tomorrow exam 😂😂

[abhinavraj]

16:15 For detection of primary alcohol group conc Hno3 is used

[ruquyyasaifi]

22:46 valine (Neutral) amino acids may be neutral acidic and basic as well

[amanstar]

sir pdf of biomolecules pyq is not available on telegram plz update it
