Question
State two molecular characteristics of substances that typically form liquid crystals. How is each related to function?
Step-by-Step Solution
Verified Answer
Liquid crystal phases are cloudy in appearance which means that they scatter light in the same way as colloids.
1Step 1: 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.
2Step 2: 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.
