Chemistry Question on p -Block Elements
S1: Be+2 has higher SRP than other alkaline earth metals.
S2: Be+2 has higher hydration energy and greater △aH (atomisation enthalpy) than other alkaline earth metals.
A
Both S1 & S2 are true
B
S1 is true ; S2 is false
C
S1 is false ; S2 is true
D
Both S1 & S2 are false
Answer
Both S1 & S2 are true
Explanation
Solution
The correct option is(A): Both S1 & S2 are true.
Be has least –ve SRP value because of high △aH (atomisation enthalpy), inspite of maximum hydration energy.
The correct option is (A): Both S1 & S2 are true.
