Can any one here please provide me the Chemistry sample question paper of ICAR UG Entrance Exam???

Here I am sharing the Chemistry sample question paper of ICAR UG Entrance Exam

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.

Phenol, when it first reacts with concentrated sulphuric acid and then with concentrated nitric acid, gives
i. p-nitrophenol
ii. nitrobenzene
iii. 2,4,6-trinitrobenzene
iv. o-nitrophenol
