Which statement explains why hydrogen bonds are able to form between water molecules?
Water molecules are polar.
Hydrogen bonds are attractions that exist between a positively charged hydrogen atom and a small, highly electronegative atom, such as fluorine, oxygen, or nitrogen, which has a pair of electrons, or a negative charge, occurs between molecules that contain those three types of polar junctions.
Hydrogen bond formation is possible in water because the oxygen in one water molecule has two free pairs of electrons, each of which can form a hydrogen bond with hydrogen atoms in two other water molecules, thanks to its polarity.
Chapter 2 Flashcards | Quizlet – c. Water can form hydrogen bonds because of its bent shape, which is the result of the polar covalent bonds between oxygen and hydrogen atoms. Which characteristic of water allows insects to walk on water? Hydrogen bonding between water molecules gives water a high surface tension that provides enough resistance for light insects to walk across.Multiple hydrogen bonds occur simultaneously in water because of its bent shape and the presence of two hydrogen atoms per molecule. In the liquid state, the hydrogen bonds of water can break and reform as the molecules flow from one place to another. When water is cooled, the molecules begin to slow down.Which statement explains why hydrogen bonds are able to form between water molecules? a. Water molecules are polar. b. Water molecules have weak bonds. c. Water molecules show adhesion. d. Water molecules are large
Hydrogen Bonding | Chemistry for Non-Majors – Hydrogen Bonds – Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond. This bond is very weak.which statements best helps explain the formation of the hydrogen bond represented in the figure? The nitrogen has a partial negative charge, and the hydrogen attached to the oxygen has a partial positive charge. hydrogen bonds form between water molecules because a positive charge and a negative charge is attracted to each other.Ø Hydrogen bond formed between two molecules is called intramolecular hydrogen bond.. Ø The bond dissociation energy of hydrogen bond in liquid water is about 23 kJ/mol.. Ø The bond dissociation energy of covalent bond between O and H in water molecule is 470 kJ/mol.. Ø Hydrogen bonds in water are very unstable and they frequently break and reform in liquid water.
Which statement explains why hydrogen bonds are able to – Start studying (a) how hydrogen bonding occurs between water molecules; properties of water and roles of water for living organisms. Learn vocabulary, terms, and more with flashcards, games, and other study tools.Third, water has a higher boiling point than HF, yet fluorine is more electronegative than oxygen, it is also smaller, and so you would expect the HF hydrogen bond to be stronger than the OH hydrogen bond. In fact, this is all try, and what this argument does not take into account is the number of hydrogen bonds.Water has many properties that are critical to maintaining life. It is polar, allowing for the formation of hydrogen bonds, which allow ions and other polar molecules to dissolve in water. Therefore, water is an excellent solvent. The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances.
