It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream.

Arrange the following compounds in order of increasing acidity, and explain the reasons for your choice of order. a. 2,4-dinitro
ludmilkaskok [199]

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
