Write the acidic strength order of following compounds co,h q. coh co h ch, (0) ch, ch,

yes, Simun do you have any doubt?

but how to know here ortho effect is work and according to +m and +I it is least stable

yes I m very confuse in this ortho effect

wait I'm explaing you ortho effect.. I'll help you

ok

can u clear out that ...all effects which are applicable for checking the acidity of compounds

first remember always ortho effect works only in benzoic acid and aniline when any group present at ortho position. “Ortho-isomer of Benzoic acid is strongest Acid as compared to Simple benzoic acid or meta & para-isomers & Ortho- isomer of Aniline is Weakest Base as compared to Simple Aniline or meta & para-isomers.”

simun you know we've already discussed about SIR effect, and now ortho effect. don't be confused with then actually SIR effect works in all the 1,2,3 tri substituted compounds while ortho effect works only in benzoic acid and aniline having groups at ortho position

so whne you see benzoic acid and aniline, and it it is ortho substitute then always ortho effect work so you don't need to be confused

now tell me if you have any confusion regarding this concept

if ortho effect is present the compound is most stable and acidic

pls tell me all effects to find acidic strength or short tricks

in case of benzoic acid it is most acidic while in case of aniline we will check basicity. it will least basic

also explain CARDIO rule for acidic strength and what is it ?

do you have clear SIR effect and ortho effect??

open above link for cardio rule.. it is nothing but combination of rules.Charge Atom Resonance Dipole Induction Orbitals = CARDIO.

hope this will help you

yes
