Detailed explanation-1: -Answer and Explanation: The following is not true about water molecules: c) Water molecules form ionic bonds. Rather, water molecules form hydrogen bonds with each other due to their polarity.
Detailed explanation-2: -Water is the most abundant molecule in the Earth’s atmosphere. The statement D, that is, water is the most abundant molecule in the atmosphere of the Earth is false.
Detailed explanation-3: -Primarily, water dissolves many substances because it contains extremely polar hydrogen bonds. The polarity of the bonds between the two hydrogen atoms and the oxygen atom means that two sides of the molecule gain different charges-one slightly positive and one slightly negative.
Detailed explanation-4: -Water is called a ‘universal solvent’ because water can dissolve much more substances than any other liquid found in nature but water cannot dissolve every substance. For example-water cannot dissolve fats, waxes, and hydroxides due to the low solubility of oppositely charged particles.
Detailed explanation-5: -Because of its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.
