Question

Give the correct order of initials T or F for following statements. Use T if statement is true and F if it is false. (i) HF boils at a higher temperature than HCl (ii) HBr boils at lower temperature than HI (iii) Pure HI can be produced by reacting concentrated sulphuric acid with KI (iv) Ka 2 of Maleic acid is higher than that of Fumaric acid

TestHub · Accepted Answer

(i) Due to intermolecular H–bonding in HF it boils at higher temperature than HCl

(ii) Mol. wt. ofHBr < Mol. wt. of HI

(iii) Conc. H₂SO₄being oxidising in nature, oxidizes HI (Reducing character) into I₂

(iv)Due to intramolecular H–bonding, in maleic acid Ka₂ is less than Ka₂of fumaric acid in which no intramolecular H–bonding is absent
