Which of the following statements regarding basicity of lanthanide `3^+` ions is correct? 1)Basicity decreases with increase in ionic radius 2)Basicity decreases with decrease in ionic radius 3)More basic oxo-salt decomposes more readily that the less basic 'oxo-salt 4)More basic ion hydrolyse more readily

A

Basicity decreases with increase in ionic radius

B

Basicity decreases with decrease in ionic radius

C

More basic oxo-salt decomposes more readily that the less basic 'oxo-salt

D

More basic ion hydrolyse more readily

Text Solution

Verified by Experts

The correct Answer is:
B
As the size of the ion is decresed it.s tendency to donate electron is decreased, causing decrease in basicity.
