The lone pair of electrons on the oxygen atom in an ester can form hydrogen bonds in some situations, but esters cannot form hyd
mixer [17]

Answer:

Esters have lower boiling point than alcohols.

Explanation:

Esters are the fruity smelling compounds which are formed from carboxylic acid and alcohol with the removal of water.

The general formula for the ester is RCOOR' which is prepared from RCOOH acid and R'OH alcohol.

Ester can not form strong hydrogen bond as there is no hydrogen attached to the electronegative atom in the ester and thus cannot form hydrogen bonds with each other.<u> Due to this factor, the interactions within the molecules of the ester is lower than that of alcohols which exist in strong hydrogen bonding. As a result, ester can be easily boiled when compared to the alcohols and thus they have lower value of boiling points.</u>

What happens to a reaction at equilibrium when a reactant is removed from the reaction system
Firlakuza [10]
When a reactant is removed based on a reaction at equilibrium, the condition favors the backward reaction. This obeys the Le Chatelier's principle which states that any disturbance in the system shall be dealt in a way that the system counters that disturbance.
