Carboxylic acids Acid/ALQ/P. 1 90(I)1.(c) E HOOC–CH 2 CH 2 CH 2 CH 2 –COOH (ii) Show how E , by reaction with suitable reagents, may be converted into an important commercial product. ( 2 marks ) 90(I)4.(c) Amides are generally prepared by reacting equimolar amounts of an amine and an acid halide. Calculate : (i) the mass ( in grams ) of Y required to react with 4.0 g of benzoyl chloride ( C 6 H 5 COCl ), and (ii) the percentage yield of the same reaction if 4.0 g of the amide product is obtained. Y 90(II)8.(a) It is suggested that the structure of a compound having the molecular formula C 12 H 11 ClO 4 is either A or B . Cl CH COOH COOH C CH 3 CH 3 CH COOH COOH C CH 3 CH 2 Cl A B (i) How would you show quantitatively, the presence of TWO acidic hydrogen atoms in the molecule ? (ii) How would you show the presence of a carbon-carbon double bond in the side chain ? (iii) How would you distinguish A from B in the laboratory ? (iv) Assuming the compound has the structure A, give the structural formula of the hydrogenation product from reaction with one mole of hydrogen. Would you expect the product to show optical activity ? Explain your answer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
