Re: IIST ISAT Answer Key

Friend have a Look Here I m Giving Sample Question of ISAT Chemistry Exam Paper2016 with Solution :

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. B2H6.2NH3is known as 'inorganic benzene'.
iii. Boric acid is a protonic acid.
iv. Beryllium exhibits coordination number of six.

Sol:Becl2and Alcl3both have bridged structure in solid phase.
B3N3H6is known as inorganic benzene.
Boric acid is Lewis acid.
Beryllium exhibits coordination number of 4


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.

Sol:

KMnO4can oxidise HCl along with oxalic acid into Cl2and itself gets reduced to Mn2+

The correct decreasing order of priority for the functional groups of organiccompounds in the IUPAC system of nomenclature is

Sol: The correct decreasing order of priority for the functional group of organic compounds in the IUPAC system of nomenclature is:

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

Which of the following factors is of no significance for roasting sulphide ores to the oxides and not subjecting
the sulphide ores to carbon reduction directly?
i. Metal sulphides are less stable than the corresponding oxides.
ii. CO2is more volatile than CS2.
iii. Metal sulphides are thermodynamically more stable than CS2.
iv. CO2is thermodynamically more stable than CS2.

Toluene is nitrated and the resulting product is reduced with tin and hydrochloric acid. The product so obtained
is diazotized and then heated with cuprous bromide. The reaction mixture so formed contains
i. mixture of o-; and p-bromoanilines
ii. mixture of o- and m-bromotoluenes
iii. mixture of o- and p-bromotoluenes
iv. mixture of o- and p-dibromobenzenes
