Water Molecule Properties and Bonds

The video tutorial explains hydrogen bonding in water and its significant impact on water's physical properties, such as high surface tension, boiling point, viscosity, and heat capacity. It describes the molecular structure of water, highlighting the role of lone pairs and covalent bonds. The tutorial further discusses water's polarity due to electronegativity differences, leading to partial charges and the formation of hydrogen bonds. These bonds, although weaker than covalent bonds, contribute to water's unique properties.

What is one of the physical properties of water influenced by hydrogen bonding?

• Low viscosity

• High boiling point

• Low heat capacity

• Low surface tension

What causes the hydrogens in a water molecule to be pushed down?

• The presence of covalent bonds

• The presence of lone pairs of electrons

• The high electronegativity of hydrogen

• The low electronegativity of oxygen

What type of bond is formed between oxygen and hydrogen within a water molecule?

• Hydrogen bond

• Ionic bond

• Metallic bond

• Covalent bond

Why does the oxygen side of a water molecule have a partial negative charge?

• Because oxygen is less electronegative

• Because electrons spend more time near oxygen

• Because hydrogen is more electronegative

• Because electrons are equally shared

What makes water a polar molecule?

• Equal sharing of electrons

• Unequal sharing of electrons

• Presence of ionic bonds

• Absence of lone pairs

How do water molecules arrange themselves due to hydrogen bonding?

• In a circular manner

• In a structured manner

• In a random fashion

• In a linear fashion

Which property of water is NOT a result of hydrogen bonding?

• High heat capacity
