Consider the following table that provides bond lengths

Chapter 1, Problem 1.71

(choose chapter or problem)

Consider the following table that provides bond lengths for a variety of C!X bonds (measured in ). X = F X = Cl X = Br X = I C X 1.40 1.79 1.97 2.16 C X 1.34 1.88 2.10 C X 1.27 1.63 1.79 (a) Compare the data for bonds of the type Csp3!X. Describe the trend that you observe and offer an explanation for this trend. (b) Compare the data for bonds of the following types: Csp3!F, and Csp2!F, and Csp!F. Describe the trend that you observe and offer an explanation. (c) When comparing the bond lengths for Csp2!Cl and Csp!I, the trends established in the first two parts of this problem appear to be in conflict with each other. Describe how the two trends oppose each other, and then use the data in the table to determine which bond you predict to be longer. Explain your choice.
