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

A solution with the pH of 13 is a Strong Base.
Answer:
2-propanol
Explanation:
From the given information
2 drops of an unknown sample were said to be placed in a test tube followed by the addition of 2 ml of ethanol then gentle mixing. They then initiate a further addition of 2 drops of potassium permanganate reagent (KMNO₄) to the test tube and mixed the contents of the test tube thoroughly. After adding 2 drops of potassium permanganate reagent, the reagent oxidizes the secondary alcohols(2-propanol) to ketone(i.e acetone) and no further reaction will take place since there are no reactive C-H bonds left. The diagram attached below shows how the reaction proceeds.
Work is done when force is applied to an object and the object moved from one its distance ( one place to another )
so Work = Force * Distance
if force is 300N and distance is 100m
then Work = 300 * 100 Nm( newton meter) = 30000J
( Joule = newton meter)
Because carbon is part of the element structure we are made of and other elements that we are made of are sulfur and nitrogen
