Chapter U2.39, Problem 1E

Interpretation Introduction

Interpretation:

The use of space-filling model is to be explained.

Concept introduction:

A space-filling model is the three dimensional representations of a molecule in which atoms are shown as spheres.

Answer to Problem 1E

A space-filling model gives idea about the relative size of the atoms and the distance between two atoms.

Explanation of Solution

In space-filling model, the radius of sphere is proportional to the radius of the atom. Center-to-center distance between two such spheres is proportional to the distance between two nuclcei. Thus space-filling model gives idea about the accessibility of different groups present in the molecule.

Conclusion

A space-filling model is useful in predicting reactivity and accessibility of different groups in the molecule.
