Briefly describe an experiment to determine what solvent is the best choice to recrystallize compound A.An organic chemistry laboratory Extraction; the extraction of crude naphtalene- benzoic acid mixture. Naphthalene is a suspect carcinogen and is toxic to aquatic life. Find an alternative pair of molecules that adhere better to the principles of green chemistry and can be separated by extraction using green' solvents. (kindly answer fully)You are given a mixture containing the three compounds shown below. Outline a procedure using a flow chart for the separation and isolation of all three compounds, using acid-base extractions. All three are solids at room temperature and are insoluble in deilonized water. You have access to all standard laboratory glassware and equipment, and the standard lab chemicals. .CO2H O,N. „NH2 HO2C napthalene terephthalic acid 3-nitroaniline
- Measure the benzene and water in the unknown solution mixture using Ultraviolet–visible spectroscopy (Uv).The purpose of this experiment is to use both extraction and crystallization techniques to separate a solid mixture of organic compounds. You will receive a packet with 1 g of a unknown (pH is basic) amide solid sample which will contain three components, one from each group: Group 1 (~50% wt): ethyl 4-aminobenzoate, ortho-toluic acid, or benzoic acid Group 2 (~40% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin Group 3 (~10% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin (but not the same as Group 2 compound) Create a lab procedure that will allow you to successfully isolate, purify, and identify the two major (Group 1 and Group 2) components of the unknown amide sample. reagents that can be used are 1M HCl, 6M HCl, 1M NaOH, 6M NaOH, diethyl ether, and methylene chlorideWhat is the separation scheme for 3,3,dimethyl-1-butene and HBr.

Explain.A student was performing an acid-base extraction of a mixture of three compounds. The three compounds in the mixture are shown below. The mixture was extracted wilth 6 M HCI three times. The combined extractions were put into a flask marked A, which was treated with 1 M NAOH till it turned basic. This was then evaporated to obtain a crystal, which we label A. The remaining mixture was extracted with 6 M NaOH three times. The combined extractions were put into a flask marked A, which was treated with 1 M HCI till it turned acidic. This was then evaporaled to obtain a crystal, which we label B. The remaining mixture was evaporated to obtain a crystal, which we label C.
