Question

Which of the following statements about Benzene (C6H6) is false:

a. Benzene contains 6 Pi electrons

b. All the carbon to carbon bonds in benzene are the same length

c. The structure of benzene can be represented by two resonance structures

d. Benzene has alternating single and double bonds

e. Benzene has the empirical formula CH

Answer 1

a) Benzen contains 6 pi electron - TRUE, since it contains three double bonds and 2 electrons per each bond

b) All the carbon to carbon bonds are of same length - TRUE, since the three double bonds are shared equally by all the six C-C bond length

c) TRUE, since the two structure will have C=C at different locations (3 each)

d) FALSE, since in actual compound, the bonds are basically sharing a partial single bond and partial double bond character.

e) The statement is TRUE, since the C6H6 has empirircal form of CH
