FREE Expert Solution

We’re being asked to predict the length of the As–Cl bond in AsCl3.

Given:

As-As bond = 2.48 Å

Cl-Cl bond = 1.99 Å


We have to determine first the structure of AsCl3.

Problem Details

The As-As bond length in elemental arsenic is 2.48 Å. The Cl-Cl bond length in Cl2 is 1.99 Å.

What bond length is predicted for AsCl3, using the atomic radii in the figure?

A periodic table shows that radius increases moving down the columns and left across the rows. Of those shown, Rubidium has the largest radius, and Helium has the smallest.
