Answer : Option D
Explaination / Solution:
No Explaination.
Q2. Homolytic fission of covalent bond leads to the formation of
Answer : Option D
Explaination / Solution:
No Explaination.
Q3. The
equivalent mass of a trivalent metal element is 9 g eq-1 the molar
mass of its anhydrous oxide is
Answer : Option A
Explaination / Solution:
Let the
trivalent metal be M3+
Equivalent
mass = mass of the metal / valance factor
9 g eq-1
= mass of the metal / 3 eq
Mass of the
metal = 27 g
Oxide formed
M2O3 ;
Mass of the
oxide = (2 x 27) + (3 x 16)
= 102 g
Q4.
In the following reaction,
The major product obtained is
Answer : Option C
Explaination / Solution:
No Explaination.
Q5. Based
on equation E = – 2.178 × 10–18 J (z2/n2)
certain conclusions are written. Which of them is not correct ?
Answer : Option B
Explaination / Solution:
Correct statement: For n=1, the
electron has more negative energy than it does for n=6 which means that the
electron is strongly bound in the
smallest allowed orbit.
