Given are cyclohexanol (I), acetic acid (II), 2, 4, 6-trinitrophenol (III) and phenol (IV). In these the order of decreasing acidic character will be
Multiple Choice Options
- A
- B
- C
- D
Step-by-Step Verified Solution
As we know that phenols and carboxylic
acids are more acidic than aliphatic alcohols thus
cyclohexanol is least acidic.
On the other hand III is more acidic than IV because
of the presence of three highly electron with
drawing NO 2 groups on the benzene ring which
makes the OH bond extremely polarized. This
facilitates the release of H + .
In acetic acid the electron withdrawing _ C | = O
group polarizes the O-H bond and increases the
acid strength.
Thus, acetic acid is more acidic than phenol or
cyclohexanol.
Thus, the order of acidic strength will be
III > II > IV > I
