In reaction II, the strong acid HCl will protonate the alcohol, making it a good leaving group. The resulting carbocation will then be attacked by the chloride ion, forming the final product. This reaction is known as an SN1 reaction, which is favored by the presence of a polar protic solvent such as water. 
In reaction IV, the strong base NaOH will deprotonate the acidic proton on the carboxylic acid, forming the carboxylate ion and water as a side product. This reaction is known as an acid-base reaction, which is highly favored due to the large acidity difference between the carboxylic acid and NaOH.
