I have provided the steps to figure out the number of atoms in the chemical compound.
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>
I believe the correct answer is A. All of the other choices except A is related or associated with chemical equilibrium and should follow Le Chatelier's Principle. We take in oxygen and it is one of the reactants for cellular respiration where one of the products is CO2 and is the one being released not O2.
