Plz explain the reason for this order .... r, -nh enu) -i (4) o0 -pr, <-ph, -asr < -ash, sbr < -sbh

got it??

what about nh3 and nr3 which has higher -i effect

here size of N is less compair to P so bulky groups on less size experience more stereic hinderence so here stereic hinderence of R dominant

so NR3+ have more -I than NH3+

more the stereic hinderence more is the bond angle right?? more is the %s character. and more is the -I effect

up to down size increase so less steric hinderence. so +I effect of R will be dominant over steric hinderence.

got it??

please accept the answer if you got it 🙏🙏🙏

ok sir

sir plz explain again .... how ph3has high -i

please send full image 🙏

Will you please respond dear 🙏

sry for the late reply

Do you know Drago 's Compound

no

These PH3 , SbH3 , AsH3. All are drago 's. Compound . They don't undergo hybridization

First see this video

ok sir

Did you watch the video

no sir

If you get time please watch this.

In phosphorus onwards steric factor don't dominate. But in case of Nitrogen steric factor is dominant.

sir why ph3 has high -i effect than pr3+

That's what I am saying. Due to +I effect of Alkyl group +ve charge on phosphorus is reduced.

so pr3is more stable

Yes Sweta

I m not getting

ph3 main Jada - I effect kyin Hoga

?

see, what happens over here is : in case of NH3+ the bond angle will be less as compared to that in NR3+ due to bulky nature of R group the repulsions increases in turn which increases the bond angle in NR3+. Now there is a relation between bond angle and %s character which is “As %s character increases bond angle also increases ( like in sp2 hybridization bond angle is 120 and %s is 33.3 whereas in sp bond angle is 180 and %s is 50)” Since % s increases thus the electronegetivty of N in NR3+ also increases thus it's a better -I group than NH3+

the trend changes on going down the group and here the electronegative factor and inductive effect factor decreases so dominance factor is here EN AND -I not steric repulsions

read this shweta👆...any doubt in this then please ask😊🙏

samagh ni aa rha sir

have you read it

this is the whole page

yes wait on copy i m explaining

see this shweta

got shweta??

please respond shweta 😊

ok sir

got shweta??

wait sir

okk😊

sir ph3+main -i effect Jada kyun hai

than pr3+

down the group size gets increases so repulsion gets less...so bond angle less and +I effect of R also comes into effect...so Ph3+ has more -I effect

ok sir

please accept the answer shweta if it helps😊🙏

ok sir

sir but r give +I effect n them how??

alkyl group is electron donating group show +I effect

then why they are considering it in -i effect

the page u send here..it is showing how variation in -I effect and how steric repulsions comes into effect in case of NR3+ and reduces down the group

ok sir

sir here nh3+ is stable than nr3+...

https://youtu.be/fbJyxlBieBc shweta see this video from 27 min you can clearly understand

after that any doubt then please ask😊

ok

thanku

😊

shweta it helps or not??

ya I got my answer sir

it really helps

some concept are there in chemistry which by example you can understand simply...so some video explanation helps in this

yes sir
