Arrange LiOH, NaOH, KOH, RbOH and CSOH in the increasing order of basic strength and give an adequate explanation for the same.

Explanation

To arrange LiOH, NaOH, KOH, RbOH, and CsOH in increasing order of basic strength, we need to understand how the basic strength of these alkali metal hydroxides changes as we move down the group in the periodic table.

### Step-by-Step Solution:

1. **Understanding Basic Strength**: Basic strength refers to the ability of a compound to donate hydroxide ions (OH⁻) in solution. The more readily a compound can release OH⁻ ions, the stronger the base.

2. **Group Trend in Alkali Metals**: As we move down the group from lithium (Li) to cesium (Cs), the size of the alkali metal ions increases. This increase in size affects the bond between the metal ion and the hydroxide ion (OH⁻).
