Sample Questions

Question 1
How do we differentiate between Fe3+ and Cr3+ in group III?
by taking excess of NH4OH solution
by increasing NH4+ ion concentration
by decreasing OH- ion concentration
both (2) and (3)
Question 2
The solubility of Mg(OH)2 is S moles/liter. The solubility product under the same condition is
4S2
S3
4S3
3S4
Question 3
The formation of gas at the surface of tungsten due to adsorption is the reaction of order
insufficient data

Question 4
For an ideal gas, number of moles per liter in terms of its pressure P, gas constant R and temperature T is
RT/P
PT/R
PRT
P/RT
Question 5
In case of nitrogen, NCl3 is possible but not NCl5 while in case of phosphorous, PCl3 as well as PCl5 are possible. It is due to
lower tendency of H - bond formation in P than N
availability of vacant d orbitals in P but not in N
lower electronegativity of P than N
occurrence of P in solid while N in gaseous state at room temperature
Question 6
Which of the following does not show geometrical isomerism?
1, 4 - dichloro - 2- pentene
1, 2-dichloro - 1- pentene
1, 3 - dichloro - 2- pentene
1, 1- dichloro - 1- pentene
Question 7
A similarity between optical and geometrical isomerism is that
each forms equal number of isomers for a given compound
If in a compound one is present then so is the other
both are included in stereoisomerism
they have no similarity
Question 8
KO2 (potassium super oxide) is used in oxygen cylinders in space and submarines because it
eliminates moisture
absorbs CO2
absorbs CO2 and increases O2 content
produces ozone.
Question 9
Arrange Ce+3, La+3, Pm+3 and Yb+3 in increasing order of their ionic radii
Yb+3 < Pm+3 < La+3 < Ce+3
Yb+3 < Pm+3 < Ce+3 < La+3
Pm+3 < La+3 < Ce+3 < Yb+3
Ce+3 < Yb+3 < Pm+3 < La+3
Question 10
Most common oxidation states of Ce (cerium) are
+3, +5
+3, +4
+2, +4
+2, +3
