Question

Please just answer part " b". Please explain your ranking based on inductive, electronegativity,resonance stability, size.

4. The following compounds can all behave as bases: NANH2 NaOH CHCH,ОН CH3CH2NH2 NH2 For each compound, draw its conjugate acid. a. b. Rank the acids in order of increasing basicity. Explain your ranking.

Answer 1

Na NH₃ or ÑHe is the strongest Base as N being small sized possen encens of election density in terms of lene paar will easily demate its lone pair to electron deficient specie. NaOH or on is stronger bare but less stronger than Nitz, as Oxygen is more electronegative than Nitragen this wants to keep encers electron density than Nitrogen in Ritz. cethyl group Then 'CH - Chat NHÀ , Que to + 1 effect of ethyl group, electron I effect deusity over small nitrogen atom increases use and this its tendency to denate electron pair Inductive and thus its tendences to its line increases - wen - Then (Cry-CH270H , Que to t I effect of ethyl group, I effect election density over orygen atom increases but since onggen is more electronegative than Nitrogen thes its line paus is les beanic as compared to nitrogen in CHACHENMA

Chec . L (resenance) (Here lene past of nitrogen atom is undergoing resenance, therefore Availability of lone pair on Nitrogen atom is very less here that is why it is least bank among all compounds). Increasing order of Baricity ? Chyret < uzrell-on <itz-CH_NH, < Naon < NaNH. Increasing order of basiesty .
