The mole fraction of each component in vapor phase of the vapor which is in equilibrium with 1 : 1 molar ratio of hexane and cyclohexane is to be calculated. Concept introduction: According to the Raoult’s law, the vapor pressure of the solution is equal to the product of vapor pressure of the solvent and its mole fraction in the solution. According to the Dalton’s law of gases, the partial pressure of a component is equal to the product of total pressure of the gas mixture and mole fraction of that component.

Question

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. CH. H₂ fo H2 H The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is HC HC HC CH The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is
