Question
Chapter 10, Problem 7ALQ
Interpretation Introduction
Interpretation:
When water in an open beaker evaporates over time the change in its vapor pressure has to be illustrated.
Concept introduction:
The phenomenon of evaporation of liquid is transition from “liquid phase” to “vapo r phase”. Almost all the liquids have the tendency to evaporate either spontaneously at room temperature without the effect of “external energy” or in the presence of external energy like heat etc.
Vapor pressure of the liquid is defined as the pressure of its vapor state that exists in equilibrium with the liquid state.

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds.
Thus, it is important to know which atoms carry unshared pairs.
Use the structural formulas below to determine the number of unshared pairs at each designated atom.
Be sure your answers are consistent with the formal charges on the formulas.
