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.My goal is to learn how to think in these questions and how to identify what forces act between molecules
@Enamine
Hapl
Me headache
But let's see
Thumbrule is : jisme attraction is not much, mostly repulsion basically due to hindrance jo hota hai molecules ke bich
In that case, positive deviation is observed
Mostly it's better to "remember" 'cause kaafi baar they "neglect" small deviations
Fir question galat hoga
Jaise first would be given as an example of an ideal solution
But isme "minor" positive deviation to hoga hi
The intermolecular interactions aren't the same now
=> Ideal Solution would be jab solute-solute and solvent-solvent interactions are same as solute-solvent interactions
To ideal solution would be solutions of liquids of the same nature
=> Now, non-ideal solutions can be divided into two based on the interactions between A-B and A-A & B-B interactions
=> +ve deviation mei A-B interaction is weaker than A-A & B-B type
So, more energy is required to break A-A or B-B type than A-B type
This happens in liquids of opposite nature
=> -ve deviation mei A-B interaction is stronger than A-A & B-B type
So, less energy is required to break A-A or B-B type than A-B type
This happens when a strong force or bond like hydrogen bonding is between A-B interaction
Yea ik that
But mai molecular forces identify karne me galti kar deta hu
Deviations ka concept samajh gaya mai
But application me atak raha
Is ratta maarna the only option?
yes bro kyunki inme apan intuition nhi mar sakte hai chnces are high apna intuition glt hoga
Ahh damn
Aise to bahot kuch bann sakta hai
Theek hai
hn but frequently asked questions ke basis pe raat lo
aur koi option nhi hai
ok
;-;
kya hua
logic dene ka aise mai try kar sakti hu par in the end itna yaad nhi rahega
koi ni ill just keep noting examples down
thnk hai
close kardo isko if you ok
achcha it might be overkill of me
but kya in sab ke
archcha ni
koi ni
