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.,rotate
i think you should look at the whole compound here not just Nitrogen
the methyl groups at nitrogen are increasing the e desnity
making it easier to donate electrons and thus increasing basic nature
that's true but the major factor is steric inhibition to resonance
or SIR / ortho effect
the first one is hindered so less resonance with the benzene ring, so less delocalisation of lone pair hence more tendency to donate lone pair to proton thus more basic
that yeah i agree but it is hindered so wont it be harder to donate e?
that kinda makes sense
the SIR thing as @Aetherfly mentioned is also a factor na
but yaha ortho me kuch hai thodi na there's just hydrogen
Guys SIR nahi hai yahan......
@Sephrina @Aetherfly @Shreyaaa~
SIR acts between bulky groups placed on ortho with respect to each other
Yahan kisi bhi compound me aisa hai?
Yeah ur right i was doubtful abt this so i didnt mention, thanks anyways
that i know cuz vo to strictly ortho pr haina
Hmm
The thing here is
2 chizein hain
Solvation
And tumhara lone pair availability
But yahan isne likha nahi hai which medium
So we'll consider gas phase
At least I think we should
agar ye consider kar liye tab to lp wali chiz main ho gyi na
Hmm vahi
Then fir bas ye dekho
par phir to circle karke vahi aagye
Charge kisme sabse jyada spread out ho sakta hai
ki lp to hindered haina
Kahan aa gaye
"Hindered" kaise hoga
Hindrance side se aata hai
aas paas dekho na
Usi atom pe groups lag rahe
Usne kaisa hindrance
Kya hai aas paas?
Benzene ring?
Vo planar hai
Uski hindrance aayegi nahi
benzene nhi
ch3
vo bhi to effect dalega na
N pe hi to laga hai vo
Side me thodi laga hai
hnn
par vo effect to karega na?
It's like saying same atom ki chiz same uspe hindrance laga rahi hai
Ye electrons repel karenge agreed
Par VSEPR ke hisab se vo already arranged hain
Those repulsions are minimised
par vsper kitna hi valid hai
Are aise to mat bolo yaar
šš
jo hai vo hai
Geometry batane me it's still a fine method
vsper is so old kon hi maanta hai usse
Nahi VSEPR me nahi hai yaar koi problem
yaha geometry ka thodi dekhrhe par
Old to newton's laws bhi hain
yaha to repulsion dekh rhe
Usi ka result to hai geometry
hn par vo confined condition pe hi work karte haina
well hn vo to hai
To aise to har chiz ki limitation hoti hai ji š
To leaving that aside
Those groups
im limitless :coolfrog:
They are already far enough to have minimised repulsion
Koi side vaale atom pe group aaya
Tab unhe uske hisab se adjust karna padega
That's hindrance
Is case me nahi aa raha
aaahhh okk
So that's not a factor
confusion ho gya tha
Koi ni
So now
N pe positive aayega
When it gives its lone pair
?
(formal positive charge)
hnn
To vo charge spread out? š
Over all those groups
All those carbons
Isiliye tertiary>secondary>primary
aaa
ok
merko bas vo hard to give out lp wali chiz smj nhi aari thi
baaki to hn ok hai'
alright thnkss
