in the hydrolysis of ethyl benzoate, describe what reagents you would use to isolate the product form the starting material:

Expert Solution

Hydrolysis of ethyl benzoate:

Ethyl benzoate + Hydrolysis -----> Benzoic acid + ethanol

Now, we need to find the reagent that separates the benzoic acid from the ethyl benzoate (starting material).

Benzoic acid in alkaline condition, it forms sodium benzoate, which is soluble in water. Therefore, we can use sodium bicarbonate to deprotonate the benzoic acid. The deprotonated benzoic acid will go into water.but the ethyl benzoate will stay in organic phase. With extraction method, we can separate the sodium benzoate from ethylbenzoate. After the separation of sodium benzoate, we can regenerate the benzoic acid with dilute HCl.

Therefore, NaHCO₃ is used to isolate the benzoic acid from the starting material.

Suppose you want to isolate viruses that infect marine cyanobacteria. Describe how you would do that compared to using the kinds of agar plates you were exposed to in this first laboratory session. Describe what parts of the procedure specifically must be changed. Would you need to consider incubation temperature differently? What kind of medium would you use to grow your cyanobacteria and phages?

You would like to isolate a mutant fern capable of growing in the presence of cadmium, which is toxic to wild type ferns. What specific part of a fern plant would you treat with a mutagen called EMS in order to be able to identify mutant ferns within the same generation? Explain your strategy, which should be able to identify mutations right away (even if the mutation is recessive). Hint: Look at the life cycle of the fern So in...

What would be the difference in reactivity if ethyl 3-methylbenzoate was treated in a reduction with NaBH4 vs LiAlH4? I know that NaBH4 is only powerful enough to reduce ketones and aldehydes, and ethyl 3-methylbenzoate has a ketone group, but I am confused as to how different LAH would be?
