Question 1 1 pts What is the purpose of utilizing brine (saturated sodium chloride solution) during the liquid-liquid extraction portion of the bromohydrination of cyclohexene? To lower the solubility of organic molecules in the organic layer. To stabilize the carbocation formed during the course of the reactions. To remove excess water from the organic layer of the reaction. To ensure that enough water is present for the reaction to generate an alcohol. Question 2 1 pts Which of the following...
