Solved: Bond Lengths in a MoleculeNatural gas used in home

Chapter , Problem 1PE

(choose chapter or problem)

Hypothetical elements \(X \text { and } Y\)  form a molecule \(X Y_{2}\), in which both \(Y\) atoms are bonded to atom \(X\) (and not to one another). The \(X-X\) distance in the elemental form of \(X \text { is } 2.04 \AA\), and the \(Y-Y\)  distance in elemental \(Y \text { is } 1.68 \AA\). What would you predict for the \(X-Y\) distance in the \(X Y_{2}\) molecule?

(a)  \(0.84 \AA\)        

(b)  \(1.02 \AA\)         

(c)  \(1.86 \AA\)         

(d)  \(2.70 \AA\)         

(e)  \(3.72 \AA\)
