Answer #1

Solution:

1) Option C

To remove excess water from organic layer of reaction.

The brine water (NaCl solution) during liquid-liquid extraction is used to remove the excess water from organic layer and pull it towards water layer.

2) Option A

All the signals are indicative for successful synthesis.

During synthesis of trans-bromocyclohexanol from cyclohexene indicates the apperance of both O-H stretching signal and C-Br stretching signals and loss of sp2 C-H stretch.

To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
