Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.multi ?
b def karega
and c too
Everything except A
bcd right
Yeah should be
just see the acidity of the H
phenol aint acidic enough
pka values
yep
Sulphonic is literally close to zero
Di nitro phenol is also 5 ke aas paas I guess
Idk exact numbers though
Basically bcd are more acidic than H2CO3
Which is the criteria to give the test
I dont remember the condition to this test fully
Ek baar revise marna padega
See it’s simple
A stronger acid giving a weaker acid as a product
With a reaction with a base
It’s favourable
summerize pls
Summary
Actually yahi hai yaar 😭
Baaki saare H2CO3 se stronger hain
Acha theek ha
Which would be the product
mereko isme kch nhi ata test ka to aache se batao
Dekho
Koi acid agar base se react karke acid hi bana raha hai
To kaisa acid ban na favourable hoga
Usse stronger
Ya usse weaker
weak?
Intuitively socho thoda san
Yes
Kyun bola ye batayo chalo
stablilty?
weak react nhi karna chega
strng karna chega
Ab agar solution basic hai……
Yeah exactly!
You got it
Then options me Jo saare hain
to isme hume strng to weak dekhna hai?
Unme se bas A hai
Which is itself weaker than H2CO3
H2CO3 banta hai when you react an acid with NaHCO3
isme mech kaisa hoga?
Acid base
Proton utha liya base ne
Will close these after sometime have to go somewhere now
Sure sure
Samajh aa gaya na?
sure
‘cause I gotta go too now
Kuch poochna hai to batayo
ye vala ik var batao na smj nhi aaya
Vahi tumne sahi bola
Basic hoga
To acid se react karna chahega
Agar stronger acid ban gaya
Tab bhi react karega
So reaction khatam kab hogi?
to is test me strong will give co2 right?
On the formation of a weaker acid
H2CO3 is H2O + CO2
Water me bubbling hoke nikal jaati hai CO2
ok okk
mtlb isme h2co3 ki formation dekhna hai right
kitna confusing hai ye
Yes
Acidity ka order yaad hona chahiye
Fir nahi confusing
vahi to nhi yaad
Pka values ki table de dein paper me to yaad bhi na karna pade
:sweaty:
Par kya karein India hai
dete kaha hai?
Periodic table bhi yaad karke khush hai sab
yaha bas yaad karlo
reason? tel lene jaaye
Are data kyun yaad karna I still don’t get
merko nhi yaad
intutionn
vahi to
Periodic table me kon si intuition laga rahi ho bua ji 😭
log inte saal faltu me mahnat karke banae ki hum ratta marre
aur koi kaam nhi hai
memory pe
aur ye kis uske compound ke hisab se kya valency hai
kay grp hai
Unhone banayi thi taaki har element alag se na yaad rakhna pade
Humne table hi yaad karli
india hai
to mumkin hai
Mai exact table ki baat kar raha tha actually
Vo bhi to yaad rakhni hu padti hai….
vo to bilkul nhi yaad
Otherwise you can’t do trends and stuff
Thoda to yaad rakhna hi padta hai yaar ab 😭
na tak hai
max ca tak
Agar table dete exam me to kabhi nahi karta yaad
Ab nahi dete to majboori hai yaad hai mujhe almost
thread nhi khrb karni chiye bhyi
abhi bahut chem bacha hai aaj ka
solution ka test deke aati
Karo karo
Mera bhi bacha hai
haao
Mai bhi jaake padhun
hnn
same
am i cooked if i dont remember a thing except the first 20 elements
😭
Kinda
Idea rakho yaar most of the table ka
F block ka understandable hai if you don't remember fully
And d block ki vo last vaali series
6d vaali I guess
It works if you don't remember that
Hm guess I better start remembering one group everyday
Hmm hmm
