Vedclass · Answer

(B) The acidity of organic compounds depends on the stability of their conjugate bases.$1$. $III$ (Cyclohexanecarboxylic acid) is a carboxylic acid,which is the most acidic among the given compounds $(pK_a \approx 4-5)$.$2$. $I$ (Phenol) is more acidic than alcohols due to resonance stabilization of the phenoxide ion $(pK_a \approx 10)$.$3$. $II$ (Cyclohexanol) is a typical aliphatic alcohol $(pK_a \approx 16)$.$4$. $IV$ (Ethynylcyclohexane) is a terminal alkyne,which is the least acidic among these $(pK_a \approx 25)$.Therefore,the increasing order of acidity is $IV < II < I < III$.

Column-$I$	Column-$II$
$(i)$ Acetic acid	$(a)$ Stephen
$(ii)$ Sodium phenate	$(b)$ Friedel-Crafts
$(iii)$ Methyl cyanide	$(c)$ $HVZ$
$(iv)$ Toluene	$(d)$ Kolbe's

What is the correct order of increasing acidity for the following compounds?
$I$: Phenol
$II$: Cyclohexanol
$III$: Cyclohexanecarboxylic acid
$IV$: Ethynylcyclohexane
