- 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 chlorideWhich statement(s) below related to the separation of a neutral compound from benzoic acid (dissolved in ethyl acetate) are correct?

- Enter the IUPAC name for the compound shown below: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. The identity of A is Select] The identity of B is (Select) The identity of Cis Select] OH NH2 3You need to recrystallize compound A. You are given several solvents to choose from.
