Given below are two statements.
Statement I Basic strength of 
but reverse is true for their bond angles.
Statement II Acidic strength of 
but reverse is true for their reducing property.
In the light of the above statements. Choose the correct answer from the options given below.
Text Solution

The acidic strength of 
because down the group, electronegativity decreases and size increase. Thus, it becomes easy to lose 
ion. Similarly, their reducing property is also in same order.
The basic strength of 
because down the group, the size of central atom increases, thereby their orbital become more diffused, hence the nucleophilicity of the lone pair is less dense over the bigger atoms, so basicity decreases. Therefore, 
is more basic than 
.
Similarly, their bond angles are in the order of
