$NaOH > Mg(OH)_2 > Al(OH)_3$

Vedclass · Answer

(C) The basic character of hydroxides depends on the ionic nature of the $M-OH$ bond. As the electronegativity of the metal increases,the $M-OH$ bond becomes more covalent,leading to a decrease in basic character. Electronegativity increases from $Na$ $(0.9)$ to $Mg$ $(1.2)$ to $Al$ $(1.5)$. Therefore,the basic character decreases in the order: $NaOH > Mg(OH)_2 > Al(OH)_3$.

The correct order of relative basic character of $NaOH$,$Mg(OH)_2$ and $Al(OH)_3$ is
