`C_6 H_5 N^(+)(CH_3)_3 OH`-is a stronger base than `NH_4 OH`. Explain.

A : When C_(2) H_(5) - O- CH_(3) is reacted with one mole of Hl then C_(2)H_(5)OH & CH_(3) I is formed . R : It is S_(N)1 reaction

Suggest a route to prepare ethyl hydrogensulphate (CH_(3)-CH_(2)-OSO_(2)-OH) starting from ethanol (C_(2)H_(5)OH) .

Calculate the molar solubility of Fe(OH)_(3) in a buffer solution that is 0.1M in NH_(4)OH and 0.1M in NH_(4)Cl (K_(b) of NH_(4)OH=1.8xx10^(-5) , K_(sp) of Fe(OH)_(3)=2.6xx10^(-39) )

(CH_(3))_(3)C-OCH_(3) on reaction with HI gives (CH_(3))_(3)C-I and CH_(3)-OH as the main products and not (CH_(3))_(3)C-OH and CH_(3)-I . Explain.

Dissociation constant of CH_(3)COOH and NH_(4)OH in squeous solution are 10^(-5) if pH of a CH_(3)COOH solution is 3, what will be the pH of NH_(4)OH ?

Consider the following compounds (1) C_6H_5-NH-CH_3 (2) C_6H_5-NH-C_6H_5 (3) (C_6H_5)_3N (4)CH_3-CH_2-NH_2 write the basicity order

Hydrolysis is an acid-basedreaction of a cation or anion or both ions of a salt with water, Resultan solution of hydrolysis may be acidic, basic or netural. The anion A^(-) which is a weakeer base than OH^(-) and which his its conjugate acid HA stronger then water but weaker than H_(3)O shown the phenomenon of hydrolysis Ex : CH_(3)COO^(-),CN^(-),NO_(2)^(-) etc. The contion B^(+) which is a weaker acid than H_(3)^(+) which is a weaker acid then H_(3)^(+) and which has its conjugate base BOH stronger than water but weak than OH^(-) shown the phenmenon of hydrolysis Ex : NH_(4)^(+)C_(6)H_(5)NH^(+),N_(2)H_(5)^(+) etc. The hydrolysis constant of anion and cation are given by A^(-)(aq.)+H_(2)O(l)hArrHA(aq.)+OH^(-)(aq) " " K_(h)=(K_(w))/(K_(a))rArr([HA(aq.)][OH^(-)(aq.)])/([A^(-)(aq.)]) B^(+)(aq.)+H_(2)O(l)hArrBOH(aq.)+H^(+)(aq.)
