Kumau university k PhD entrance k previous year question paper kra dp
Chemistry?
@@Chemistry_ResearcheR yes for chemistry
Sir uttrakhand combined PhD entrance chemistry k ly kha s pdhe
Sir Physics ka kaise milega
sir paper dedijyw
Join my telegram group with same name
sir maine join kiya but mujhe phd ke papera nhi milre
Abhi chek karo maine name lhik diya hai usme PhD entrance karke 6 July date dhekna

Sir kitne cut off aayi h obc ki
No idea but bhot high gyi h bcoz obc female me 176 mkx me bhi selection nhi hua h
thank you sir
Sir Cut off ky rhegi ...koyi idea .....OBC
Kitne mkx ban rahe hai tumhare
Sir mere 75quation Shi ho rhe hai ....150
Ab Isme 3-4 quation or Shi ho skte hai
Ho jayega..fir tumhare bcoz abhi ans key revised hogi... So or increase ho jayenge mkx
Kha se ho tum Haldwani ya khi or se ?
Sir, 0.1% NaOH solution kyse banaye
Divide the amount by 10 like 1/10gm = 0.1 gm
Sir toh , 0.1g NaOH le kar k उसे 10ml water me dissolve karna hoga
Yes
0.01 g in 10 ml
20% NaOH kaise bbanayege
Kisi ne koi ques chlnz kia h kya
Yes ye 3 questions challange kiye h
Sir what about no. Of carbonyl stretches in 2-hydroxy-3-nitro acetophenone ?
Bo sahi hai do frequency hai 3608 nd 3605 par ye hai link u can check www.google.com/search?q=carbonyl+streching+frequency+in+-+hydroxy+3-nitro+acethophenone&oq=carbonyl+streching+frequency+in+-+hydroxy+3-nitro+acethophenone&gs_lcrp=EgZjaHJvbWUyBggAEEUYOTIGCAEQIRgK0gEJNDQ3MTZqMGo0qAIAsAIA&client=ms-android-xiaomi&sourceid=chrome-mobile&ie=UTF-8
@@Chemistry_ResearcheR thank u for this reply sir
Degenracy wala b to hai sir 6 ans nhi hoga
Nahi bo sahi bcoz bo statistical thermodynamics ka question hai degeneracy= 2J+1
Ok
Kitni jayegi sr cutoff UR ki?
Fir ur should be 160 to 170
1.Azulene and [14]- Annulene both are non benzenoid aromatic compounds.
Yes u r correct
Is par objection dija ka sakta hai
yes... One question is also there... How many carbonyl stretching frequencies are possible in 2- hydroxy 3- nitroacetophenone The answer should be 1.. because only one carbonyl group present in this molecule.. but the answer is 2 how is it possible?
In logo ne bachho ke sath khilwad kiya hai bhot sare ans galat diye hai abhi quatum ka bhi ek question wrong diya hai and kitno par objection kare per question ka 1000 charge had hoti hai.. bs loot rahe hai.. or jindagi ke sath khilwad kar rhe hai
Google m 2 aaya yr@@sanjaysinghbisht9088
👍
and there is question about ICL3 I thik it may be wrong in ans key please check
Yes u r right
please provide references fo challenge
Abhi thodi der me reference provide krta hu video upload krta hu thodi der me
And sir please look at the questions about Icl3 once ..
Yes these 3
u r the rising star of future
Sir is q paper ke answer key bata dijiyega
Thik hai bta dunga mai.. evening tak kitne questions thik hai tumhare chemistry me is ans key ke according
Sir tell me important question of chemistry bsc 3rd year
Congratulations 🎉 sir
