Question
Chapter 12.4, Problem 1PPC
Interpretation Introduction
Interpretation:
The changes required to convert the given compound to a liquid crystal compoundare to be determined.
Concept introduction:
Liquid crystals act like both conventional liquids and solid crystals.
Liquid crystals have the ability to flow and take the shape of the container like liquid, and also have a regular arrangement of particles in the lattice like solids.
Liquid crystals scatter light.
Some substances exhibit liquid crystal behavior when they are melted from solids.
As the temperature increases, the solid liquifies but retains some order in one or two dimensions.

If the density of the compound is 4.51 g/cm^3 and the ionic radius of Cs + is 169 pm, what is the ionic radius of I − in pm? Key Concept: The atoms are touching the diagonal in the center of the cube. This makes it equal to the sum of 2 times the radius of each atom. Strategy: Determine the length of the diagonal,d, and recall that the length of the side, l, is given by l = d/3 0.5. This is a result of the use of the Pythagorean theorem relating the length of the side to d.With the length of the side you can determine the volume of the unit cell.From the number of atoms in the unit cell determine the mass of the unit cell.Use these to get the density.arrow_forward
