Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(a) Acidic sterngth of HBr > HCl and their reducing proeprties are also in same order.

(b) Basic strength of PH₃> AsH₃, their bond angles are also in same order



(c) ${\text{θ}}_2>{\text{θ}}_1$because bond pair in C-F is held more close to F atom than bond pair in C-Cl bond. B.P - B.P repulsion less in CH₃F i.e.$\text{H}\widehat{\text{C}}\text{H}$bond angle is more.



(d) ${\text{K}}_{{\text{a}}_1}$of maleic acid is higher than${\text{K}}_{{\text{a}}_1}$of fumaric acid but reverse is true for their${\text{K}}_{{\text{a}}_2}$.


In maleic acid after loosing H⁺ion intramolecular hydrogen bonding taking place so, H⁺removal is easy hence, k_a1will be higher for maleic acid
