CH 4 4.91 HW 6TH EDITION

[Jeremiah Hutauruk]

4.91 Benzyne, C6H4, is a highly reactive molecule that is detected only at low temperatures. It is related to benzene in
that it has a six-membered ring of carbon atoms; but, instead of three double bonds, the structure is normally drawn with two double bonds and a triple bond. (a) Draw a Lewis structure of the benzyne molecule. Indicate on the structure the hybridization at each carbon atom. (b) On the basis of your understanding of bonding, explain why this molecule might be highly reactive.
