Identify correct acidic strength order in the following compounds: ho ho oh ho oh oh b b no2 (i) (i) no no a) i> ii> ill b) ill> il> 1i c) i>ill >il d) ll>1>il

Option B is correct In IIIrd there is resonance but no steric crowding...So most acidic. Acidity order will be III>II>I check this pka value

option C is correct. here NO2 shows both -R and -I effect at orho and Para compounds. so acidity of both ortho and Para compounds will be greater than meta. ortho will be more acid...

C is the correct trend here, I think. -NO2 has strong -I and strong -M effect which operates through ortho/para positions. Electron withdrawing nature is more pronounced at ortho t...
