Test 1-Tables

Bonds and Interactions:

Sharing of electron pairs; Strong

Bonds and Interactions:

Attraction of opposite charges

Bonds and Interactions:

Sharing of H atom

Bonds and Interactions:

Forcing of hydrophobic portions of molecules together in presence of polar substances

Bonds and Interactions:

Weak attraction between atoms due to oppositely polarized electron clouds

The properties of water:

Hydrogen bonds hold water molecules together

The properties of water:

Hydrogen bonds absorb heat when they break and release heat when they form, minimizing temperature changes

The properties of water:

Many hydrogen bonds must be broken for water to evaporate

The properties of water:

Water molecules in an ice crystal are spaced relatively far apart because of hydrogen bonding

The properties of water:

Polar water molecules are attached to ions and polar compounds, making these compounds soluble
