Daily Video 1.1: Structure of Water and Hydrogen Bonding

What is the chemical structure of water?

One oxygen, Two Hydrogen

How does the chemical structure of water result in polarity?

oxygen’s electronegativity attracts more electrons to its area than the less electronegative hydrogen

How does water’s polarity result in cohesion and adhesion through hydrogen bond interactions?

the uneven polarity allows it to form hydrogen bonds with other molecules

What chemical characteristics of water result from its cohesive and adhesive properties?

What is a covalent bond?

a type of bond in which atoms share electrons

What is polarity?

a difference in electronegativity that results in an unequal sharing of electrons

What is a hydrogen bond?

a weak bond interaction between the negative and positive regions of two separate molecules

When can hydrogen bonds with water form?

with other water molecules or other charged molecules

What is cohesion?

when two of the same molecule form hydrogen bonds with each other

What is adhesion?

when two different molecules form hydrogen bonds with each other
