Which alkaline earth metal hydroxide is the most basic?

Options

  1. ABeryllium hydroxide (Be(OH) 2 )
  2. BMagnesium hydroxide (Mg(OH) 2 )
  3. CCalcium hydroxide (Ca(OH) 2 )
  4. DBarium hydroxide (Ba(OH) 2 )

Correct answer

D. Barium hydroxide (Ba(OH) 2 )

Step-by-step solution

Barium hydroxide (Ba(OH) 2 ) is the most basic among the alkaline earth metal hydroxides. As you move down the alkaline earth metal group in the periodic table, the basicity of the hydroxides increases, and barium hydroxide has the highest basic character due to its position at the bottom of the group.
