For this question, you will consider the four molecules CH4, NH3, BH3, and H2O. Refer to your Lewis structures and your notes on the molecular polarity for these molecules. What features do the polar molecules in this group all have in common

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
