Compounds in order of increasing acidity will be written as d<c<b<a.
<h3>What is acidity?</h3>
The quantity of hydroxyl ions that a basic molecule may create in an aqueous solution is what is known as the acidity of bases. The quantity of hydronium ions that a substance may create in an aqueous solution determines how basic an acid is.
a, b are more acidic than c and d because of OH group attached to sp2 hybridised carbon which provide resonance stability for conjugate base
in c f has -I effect which increases acidity in a, NO2 has -m effect which increases acidity so increasing order is d<c<b<a
that is cyclohexanol < 2,4-difluorocyclohexanol < phenol < 2,4-dinitrophenol
