Question

Ethanol is $C{H}_{3}C{H}_{2}OH$. Which species is formed when ethanol acts as a Bronsted base?

• A. $C{H}_{3}C{H}_{2}O$
• B. $C{H}_{3}C{H}_2^{+}$
• C. $C{H}_{3}C{H}_{2}O{H}_2^{+}$
• D. $H_3{O}^{+}$

Answer 1

The correct option is C $C{H}_{3}C{H}_{2}O{H}_2^{+}$

A Brønsted-Lowry base is a proton (hydrogen ion) acceptor. When ethanol acts as a Bronsted base, the species formed is $C{H}_{3}C{H}_{2}O{H}_2^{+}$
The reaction is shown below.
$C{H}_{3}C{H}_{2}OH+H^{+}\to C{H}_{3}C{H}_{2}O{H}_2^{+}$
Hence, the option (C) is the correct answer.
