HCI, HN $O_{3}, C_{2} H_{5} O H, C_{6}, H_{12} O_{6}$ all contain H atoms but only HCI and $H N O_{3}$ show acidic character. Why ?

Solution

It is because of the reason that in HCl, HNO₃ there is availability of acidic hydrogens (H⁺ ions).That is complete cations and anions formed, so that they are treated as acids.
But in the case of C₂H₅OH, C₆H₁₂O₆the formation of acidic hydrogens is not possible. In the case of C₂H₅OH the formation of acidic hydrogens is slightly possible so it can be considered as weak acid.
