Using Friedel Crafts alkylation of benzene, a group of scientists discovered
compound A, CsH10, an optically inactive compound. They discovered that
compound B, C3H9Br, is produced during the halogenation process. When
compound B is reacted with nitric acid, compound C, C3H§BrNO2, is formed.
While Friedel Crafts acylation of compound A produces compound E, C10H12O.
This compound C was oxidised to produce compound D, C,H4BrNO4 as a major
product.
Identify the possible structural formulae compounds A to E and explain your
answers.
The following compounds are given to you:2-Bromopentane, 2-Bromo-2-methylbutane, 1-Bromopentane(i) Write the compound which is most reactive towards SN2 reaction.(ii) Write the compound which is optically active.(iii) Write the compound which is most reactive towards P-elimination reaction.
When 2-bromo-2-methylbutane is treated with a base, a mixture of 2-methyl-2-butene and 2-methyl-1-
butene is produced. When potassium hydroxide is the base, 2-methyl-1-butene accounts for 45% of the
product mixture. However, when potassium tert-butoxide is the base, 2-methyl-1-butene accounts for
70% of the product mixture. What percent of 2-methyl-1-butene would be in the mixture if potassium
propoxide were the base?
