The set in which compounds have different nature is :
Solution
<p>(A) Both are acidic in nature.
<br/>B(OH)<sub>3</sub> is orthoboric acid. It can accept a pair of electrons from Lewis bases and hence, act as Lewis acid.
<br/><br/>H<sub>3</sub>PO<sub>3</sub> is (phosphorus acid) diprotic acid as it readily ionises two protons. </p>
<p> (B) B(OH)<sub>3</sub> is acidic and Al(OH)<sub>3</sub> is amphoteric in nature.
<br/><br/>(C) Both NaOH and Ca(OH)<sub>2</sub> are basic hydroxides.
<br/><br/>(D) Both Be(OH)<sub>2</sub> and Al(OH)<sub>3</sub> are amphoteric hydroxides. <br/><br/>Hence, only B(OH)<sub>3</sub> and Al(OH)<sub>3</sub> have different nature. </p>
