Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: \[{{H}_{2}}\] molecule is more stable than \[HeH\] molecule. Reason: The anti-bonding electron in the molecule destabilize it.A) If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:.
B) If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:.
C) If Assertion: is true but Reason: is false.
D) If both Assertion: and Reason: are false.
Correct Answer: B
Solution :
\[{{H}_{2}}\] molecule is more stable than HeH because bond order of \[{{H}_{2}}=1\] ad that of \[HeH=\frac{1}{2}\] (Higher the bond order, more is the stability).You need to login to perform this action.
