Question

Match the formulas given in Column A with the correct names In Column B: Which of the following is not true concerning the structure of benzene? (There is only one correct answer). All C-C-C bond angles are exactly 120 degree. The carbon-carbon bond lengths are all equal The six hydrogens are equivalent. There is a rapid equilibrium between structures in which the carbon-carbon bonds alternate between single and double bonds (as shown below): For the reaction R-X + OH^- rightarrow R-OH + X^-, which of the following expressions is the experimentally observed rate law? Rate = K[OH^-] Rate = k[RX)^2 Rate = K [RX] [OH^-] Rate = k [RX]

Explanation / Answer

1

a. Phenol

b. Benzaldehyde

c. Styrene

d. Benzoic acid

e. Toluene

f. Aniline

2. The answer is d

The a, b, c are all correct statement regarding the structure of benzene

3. b

For a bimolecular reaction, the rate of the reaction depends on concentations of both the reactants.

Rate = k[RX][OH-]
