You are looking for Andhra Pradesh Engineering, Agriculture and Medical Common Entrance Test model question paper, here I am giving:

Q. 1. Which one of the following is the correct statement?

i. Chlorides of both beryllium and aluminium have bridged chloride structures in solid phase.

ii. B2H6.2NH3 is known as 'inorganic benzene'.

iii. Boric acid is a protonic acid.

iv. Beryllium exhibits coordination number of six.

Sol: Becl2 and Alcl3 both have bridged structure in solid phase.

B3N3 H6 is known as inorganic benzene.

Boric acid is Lewis acid.

Beryllium exhibits coordination number of 4



The pKa of a weak acid, HA is 4.80. The pKb of a weak base, BOH, is 4.78. The pH of an aqueous solution of

the corresponding salt, BA, will be

i. 7.01

ii. 9.22

iii. 9.58

iv. 4.79



Amount of oxalic acid present in a solution can be determined by its titration with KMnO4solution in the

presence of H2SO4. The titration gives unsatisfactory result when carried out in the presence of HCl, because HCl

i. reduces permanganate to Mn2+.

ii. oxidises oxalic acid to carbon dioxide and water.

iii. gets oxidised by oxalic acid to chlorine.

iv. furnishes H+ ions in addition to those from oxalic acid.



Among the following substituted silanes the one which will give rise to cross linked silicone polymer on

hydrolysis is

i. R2SiCl2

ii. R3SiCl

iii. R4Si

iv. RSiCl3
