What does it mean when a molecule is described as “polar?”
Polarity is defined as the separation of electric charge that creates a molecule or its chemical groups with an electric dipole or multi-pole moment.
State and explain two reasons that water molecules are essential to life because of their hydrogen bonds.
The unique properties conferred to water like high boiling point, high melting point, high heat of vaporization, high surface tension, and high heat capacity are due to hydrogen bonding. The high heat capacity conferred to water by hydrogen bonding enables it to change temperature slowly after gaining or losing energy. The high cohesion forces in water due to hydrogen bonding gives it the important characteristics.. These forces are important for transportation of water to plants. The Strong capillary force which includes both cohesion and adhesion is crucial to plants in the effective transport of water.
