✨Acidity - I | GOC Class 11 | Lecture 8 for JEE Main, Advanced, NEET 2024

In this video, we are going to understand concepts of Acidity in Organic Compounds and Feasibility of Reactions in General Organic Chemistry and also solve problems of JEE Mains 2024 and JEE Advance, also we will talk about detailed mechanisms with different questions. A detailed analysis will be done by Sachin Rana sir.

​@@SajadAnsariphenyl act as -I effect this is like this compound is already beggar due to positive charge and phenyl keeps on withdrawing electrons and ch3 act as +I effect it keeps on donating electron and reduce its positive charge and third one due to crowding its stability decreases

[@jakelong-o6b]

​@@aasthagoyal1003No actually you are wrong as resonance is way more dominating effect in comparison to inductive effect and also it is a purely planar compound as you can see there are only sp2 carbons in it so there is no crowding at all, this result of b being more stable than a is an experimental data based on enthalpy change.

Z11- c(resonance from two sides)>b(resonance from two sides but +I from bridge carbon) > d(resonance from one direction and no +I)>a(resonance from neighbour oxygen and +I from bridge so least stable) and this compound follows bredts rule as it has x+y+z=9 so splitting to an extent is possible

[@mathophile716]

It was yet another amazing session (1:11:09) Z11 (c>b>d>a) my reasoning being: c and b have 3 reso structures (here bredt's rule is not violated) so they are better than d and a as they both have 2 reso structures but in b and a there will still be some strain due to which they will have a bit less stability.

[@raj12985]

bro can you explain why the bredt rule is not violated...... here I my opinion it is violated similary kind of situation is there for the question on previous slide

[@vedanteditz2006]

​​@@raj12985bro because x+y+z is 9 and z is also not 0 so bredts rule is not violated . See the previous lecture

bro why will b and a will have extra strain?

[@VivaanArora-bh7pn]

@@MarshieMaster the explanation of strain is WRONG. c is more stable than b because the the carbon is middle of bridge head applies +I effect

In homework question resonance is possible at both a and b acc to bredts rule Hb has more resonance (discontinous but more) than Ha Hc has less +I than Hb but same resonance Hd has less +I than Ha but same resonance So acidity order of h is : C>B>D>A

14:53 here for G question, if we check electronegatvity then F>O>N>C so it means that F is less likely to donate H than O and so on. Also acidity depends on willingness to donate H+ ion right ? So shouldnt order be ulta

[@Abhay-me4zi]

Here you are confused I guess... Electronegativity is the measure of an atom to keep electrons with itself not the H atom.... Also as you see since F is highly electronegative so F minus ion is highly stabilised....

[@vedanteditz2006]

Bhai dpp ka kuch galat ans araha hai ?

[@vedanteditz2006]

Aur sp2 ke karan acidity kyo kam hui

[@MarshieMaster]

​@@vedanteditz2006 Reason for sp2 acidity less than sp 3: sp2 carbon can pull the electrons away from the H more strongly, it means that the H is more tightly bound to the sp2 carbon than the sp3 carbon. This makes the H less likely to leave and form H+. On the other hand, if sp3 pulls the electrons from H less strongly than sp2, it means that the H is more loosely bound to the sp3 carbon than the sp2 carbon. This makes the H more likely to leave and form H+.
