How to decide the Relative Strength of Acids and Bases ? - Part 1

[@nilamdeka5721]

Sir in a group as you move down the group the electronegativity decreases.

[@hannahbanana2311]

yeah ikr??

[@jackyjack9660]

But the size increases due to which density of charge decreases and thus stability increases...

[@jacelemke3006]

Size increases though, in acid and base reactions we focus on electronegativity AND size instead of just on electronegativity.

[@muhammedfaizan8318]

But Sir, the more electronegative atom with nagtive charge is more stable

[@irfatullah5311]

But in across the period is most stable

[@Galeanom11]

Thank you very much, you explained it very clearly and well!

[@shardabansod5399]

watch in 1.25x thank me later

[@Faizans6]

😂

[@bhargav6908]

Thank you

[@alishashaik4711]

What's there ???

[@ephemeralsoul605]

😂😂

[@baranibhalaji8354]

Thanks broo

[@hassanacademy14]

Sir at 10:25 which one more basic ethyl one ?? Please reply someone

[@jyotimuvel686]

most acidic among AS2O5 Sb2O5 N2O5 P2O5?

[@ektasrivastava7194]

Thanks 🙂 so much.. much needed it was

[@saravananKS26]

Sir ..compare to CH3-and, Nh2 - some teachers told me Nh2-which is more basic than ch3- because Nitrogen having lone pair of electrons ...so I have doubt sir can you please explain sir?

[@IITJEEChemistryCourse]

Hi Saravanan, CH3- will be more basic than NH2-. For questions like these, think where will the negative charge be more unstable. On the C atom. Another way to think about it is by making their conjugate acids i.e. CH4 and NH3. Now, it is easier to take out H from NH3 than CH4, or NH3 is more acidic compared to CH4. Hence their conjugate bases will have the reverse order. Due to the lone pair, NH2- will be a better nucleophile, but as far as base strength is concerned, CH3- is stronger.

[@er_maheshkumar4320]

Whose basic strength ins increase OH and H2O

[@fariyazshaik3402]

OH has more basicity than H2O

[@ArunKumar-dv8zw]

OH is a better lewis base as it has higher electron density and is relatively less stable than H2O.

[@hamidullahmarwat5529]

Sir likin ye rule b to hai k agar more negative charge pa negative charge ayegaa to wo more stale hogaa......ab ee all know that Flurine is more negative ab agar us pa aur negative ayegaaa to o more stable hojayega aur dusra ye k siza b chota hai as compared to Iodine.....pir yahaan pa Iodine negative ion q stable hai...?plzz sir guide karain

[@sikhu976]

really appreciable Sir..

[@nanihobo1416]

You are great sir we need more people like you.

[@IITJEEChemistryCourse]

Thank you!

[@ruthjohn2781]

Sir at 7:53,Stronger base between OH n SH ,negative charge was on H & S.....right? n not on O as as mentioned(Atom carrying the charge ) or have I understood wrong?

[@IITJEEChemistryCourse]

Hi Stephen, Negative charge is on O and S. Negative charges in any species are usually present on the more electronegative atom (in this case O vs H). H will have negative charge only in the hydride ion( H- ).

[@swaramalika]

U are amazing thank you

[@komalshahzadi9032]

Sir in period negative charges stable and in groups negative charges also stable than what's the difference?

[@kaur3429]

Ys sir..plz tell

[@srushtikadam2156]

Basic character and basicity aren't the same, right?

[@sudhagowri8423]

Same

[@shikharsingh156]

To the point 👏

[@simransingh6512]

Thanks..it is very help full..

[@BIOLogyEgy]

What's that sound at 8 : 24... #Alienic by the way THANKYOU Very much

[@onedayiwillgotosouth-korea6854]

SAJID RAHMAN he just speeded the video up

[@closetoheart6120]

Hn bhai shi bat h

[@nizzle1931]

Five minutes into your video you are comparing stability with basicity. You said that the farther right an atom is on the periodic table, the more stable but less basic it is. Please correct me if I am misunderstanding, but you said that -NH2 is less basic than -OH despite that oxygen is farther right than nitrogen. Shouldn't it be the other way around?

[@IITJEEChemistryCourse]

NH2- is more basic than OH-. That's what I've said in the video. The basic strength is opposite to that of stability. So, OH- will be more STABLE than NH2-.

[@nizzle1931]

Re-watching your video I am seeing my misunderstanding. Also I had very little sleep while watching your video due to studying for an exam so my sense of judgment and understanding was poor. Thank you for the feedback!

[@nitink3364]

Busting JEE Main What about -PH2 and -OH

[@nanihobo1416]

Good strategy for making chemistry interesting because i love suspense.

[@doraiswamymurali8762]

Super sir

[@aditikeshri8690]

Thankusooomch.....

[@vinodshirodkar2115]

Thank u so much

[@mohanlalchoudhary560]

Awesome b'T plz make video in *HINDI LANGUAGE*

[@preetigupta9215]

thanx for clearing my doubt

[@easy-peasy9906]

You are reversing stability for finding order of acidity or basicity But in sloving qs you didnt

[@vikasrabha2965]

Thank you sir for your lesson

[@zuhairreza]

Thanks! :)

[@armankinikhla9669]

Strength of Base is opposite to the acidic strength...I'm so confused with this...can you please help me.am I right

[@jintumonideka7583]

Tqqq soo much sir I have learnt too much in 10:30👍👍

[@sounakbanerjee1138]

Stability increases down the group But in ncert it is written opposite

[@akashgautam757]

thanks a lot

[@ishaqahmad5829]

Electron affinity decrease down the group than who stability increases

[@arshilmahamadshafivahora7170]

Thx sir

[@Manish-rl6me]

Second last one is wrong

[@sunillimbu9530]

Carbon is in right side not i n left bro

[@IITJEEChemistryCourse]

I am talking about their position in the periodic table. Please check there. You will find C to the left of N

[@dreammamc6751]

Sir student ko wrong Kyo padha rahe ho basicity ka order apane galat bataya hai jo basic hota hai uski basicity sabse kam hoti hai acid ki sabse Jyada Hoti Hai basicity basicity 😐

[@Manish-rl6me]

Ch3ch2 is more basic

[@amitgaikwad8002]

Galat sikhaya hai

[@simransingh6512]

Achha ...to tum sahi sikha do...

[@dreammamc6751]

Yes bro basicity ka order galat bataya hai Jo basic Hota Hai uski basicity sabse km hoti hai acid ki sabse Jyada vaise basicity hoti hai.

[@jyotimuvel686]

most acidic among AS2O5 Sb2O5 N2O5 P2O5?

[@josechemistryintamil11than53]

Super sir
