Question

ave the (4 pt) pKa 1.96 рКа 9,89 acid (HCHO2), pKa 3.74 5. Circle the strongest acid in each of the following groups (rows). (18 pt) a. H2S H20 H2Se НЕТе b. H20 HF CH4 NH3 C Hхо4 HXO2 нхоз HXO d. HAtO HCIO HIO HBro NH4 CsHsNH CoHsNH3 e. NHs, Ko 1.8x10- CSHSNH, K 1.7x10- CaHsNHa, K = 3.8 x 10-1 OH OH OH OH 6. Three oxoacids with the formular il strength:

Answer 1

(a) H₂Te

acidity for group 16 Hydrogen chalcogenide increases down the group

(b) HF

HF is a known strong acid aamonia is known to be basic and H₂O, CH₄ are very week acids

(c) HXO₄

The acidic strength increases with increase in the oxidation number of halogens.

(d) HClO

Acidity decreases down the group after Cl for hypohalous acids.

(e) NH₄⁺

It has least value of Kb and therefore when it accepts a hydrogen ion it is least stable and it have highest tendency of giving proton.

(f) first compound

As Fluorine have highest -I effect among them all so ionised form after giving proton will be most stable .
