Chapter 12: 12.104P (page 497)

State two molecular characteristics of substances that typically form liquid crystals. How is each related to function?

Short Answer

Expert verified

Liquid crystal phases are cloudy in appearancewhich means that they scatter light in the same way as colloids.

Step by step solution

01

Definition

Liquid crystal is a matter that is intermediate between crystalline solids and conventional liquids.

The molecular characteristics that form liquid crystals are a rod-like molecular structure and strong dipoles and/or easily polarizable substituents.

02

Functions

A rod-like molecular structure keeps the molecules extended.

A molecular dipole is associated with the molecules to align along the director on a long-range basis.
