Give reasons for the following:
$(i)$ Why is it recommended that acid should be added to water and not water to acid?
$(ii)$ Why do compounds like alcohol and glucose not show acidic behavior even though they contain hydrogen?

(N/A) $(i)$ The process of diluting a concentrated acid is a highly exothermic reaction. If water is added to a concentrated acid,the large amount of heat generated can cause the mixture to splash out,potentially leading to severe acid burns.
$(ii)$ Compounds like alcohol and glucose contain hydrogen,but they do not dissociate to release hydrogen ions $(H^+)$ when dissolved in water. Since acidic behavior is defined by the presence of $H^+$ ions in an aqueous solution,these compounds do not exhibit acidic properties.
