17. the correct basic strength order of the following anion is: (a) ch3-ch2> nh2 > ch2=ch >ch=c> oh >f (b) nh2> ch3-ch2> ch:=ch> ch=c>f>oh (c) ch3-ch2 > ch2=ch

but in ans, option A is given as answer

https://youtu.be/69AyGv7dL2Q

See this.

Option B is right, Sourav.

Given answer is wrong.

sir according to the video you shared, option A is correct given on YouTube

Yes A is correct

Got it Sourav

Now you got the problem.

Any more information

Q18 option A is correct Sourav

how sir

Apply the same concept: more the stability of anion more will be the acidity

Q19 option B is correct

NH2 more basic than CH2?

yes

you know conjugate base of weaker base is strong acidic

conjugate acid of weaker base is more acidic

yes

so arrange them in acidity order. weaker acid will give strong base. i.e., basicity order of CB will be reversed of acidity

got it??

i have to first convert them. into acids by adding hydrogen?

yes

wait I'm sending full Sol

option A is correct

how

I've solved check it??

what's answer given in you booklet??

i didn't get any soln sir..ans in booklet is C

there is something problem in this app

may be later it can fix

option A or C?

match the option according to this

acidity of C2H2 is greater than NH3 so NH2- will be strong Base

option C

sorry by mistake i say A, it's C

in starting i say option C. it's correct

sir plz ans rest qs

Option C is correct

This is acidity order

Hence it's reverse will be the basicity

Now you ask your doubts.

Sorry for the confusion.

See here basicity will be defined by the stability of anion. More stable the anion less will be the basicity

Acidity is determined by the stability of the anion formed. Hence relate the two

Sourav got it

please respond

i cant understand how NH2 more basic than CH2

Now you tell me -ve is stable where

More stable is the negative charge less is the basicity

negative charge more stable on nitrogen?

Right Sourav. Hence what will be the basicity then Sourav

and between C2H and NH2?

There is theory eletronegativity jump rule I suppose which says sp carbon is more eletronegative than sp3 nitrogen. Similarly sp nitrogen is more eletronegative than sp3 oxygen.

So sp C2H is more eletronegative than sp3 NH2-

sir i need ans for rest qs
