4. (10 pt) Arrange the following compounds from left to right in terms of basicity from low to high. 5. (5 pt) Arrange the following compounds in terms of pKa values from low to high, left to right. O= HO = OH

Answer 1

Arrange the following compound from left to right in terms of baricity from low to high. z Baxicity depends om the availability of tone pair on the basic Nitrogen (W) atom. If lone pairis more available than basicity also high. If lone pair is vers available for donation Than basicity also lowers. lone pair (e-p) is not available for l.p.3com donation. It is engaged with the three to maintain the Benzene ring aromaticity, so it is less Available (Joe Dajcity) with the Bemene zing availability increases to some extent | The ep, is more available compare to other (Highest Basicity) Resonance with Renzenering Here the more basic mitrogen 13 the sing witoogens afem. only Bopropyl Basicity highem Basscity decreases due to the resonance to some extent of amine group. diee to the ti e a Bartcity (6) , B there is no enhameing group. In @ There is a Bancity decreasing group,

5. he following compound in terms of values from low to high, reft to right, We know for bemorc acid or othe substituted benzoicaird the acidic functional group is-cool, the acidity depends m the carboxylate "c-c00g) resonance (-360 D ERO stability & any other resonance with the carboxylate group decrease the ceidity of the cool group. We know that pka value o ineversely proportional to Пu штату, So, @ 300 CM 9XT earboxylate resonance's not disturbed a tall OH Corbexylate resonance is disturbed by the phenolic colt grocep
