Question

Which of the following does not give $H^{+}$ ions in aqueous solution?

• A. $H_{2}C{O}_3$
• B. $C_2{H}_{5}OH$
• C. $C{H}_{3}COOH$
• D. $H_{3}P{O}_4$

Answer 1

The correct option is B $C_2{H}_{5}OH$

$C_2{H}_{5}OH$ is a covalent compound. Ethanol has two different types of bonding between its constituent atoms. The bonds between the hydrogen and carbon atoms are nonpolar covalent bonds. The hydrogen-oxygen and carbon-oxygen bonds are polar covalent bonds. In these bonds, the electrons are more attracted to the oxygen, but it doesn't give $H^{+}$ ions in aqueous solution.
