Identify the error in this statement: “If a reaction transfers energy to the surroundings the product molecules must have more energy than the reactants”

See explanation

Explanation:

A reaction may be exothermic or endothermic. In an exothermic reaction, energy is given out from the reaction system. This means that energy is transferred to the surroundings and the reactants have more energy than the products.

A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. In this case, the products have more energy than the reactants.

So the statement "If a reaction transfers energy to the surroundings the product molecules must have more energy than the reactants” is erroneous. The error in the statement is the part that says "...the product molecules must have more energy than the reactants”. It ought to have read, "the reactants have more energy than the products" in accordance with the explanation above.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
