Question

• Some crystalline solids on heating
first form smectic liquid crystals,
which on further heating form
nematic liquid crystals. Which of the
following is the example of such type?


Answer
A. Cholesteryl benziate
B. Cholesteryl formate
c. Cholesteryl myristate
D. n-octyl p-azoxy cinnamate​

Answer 1

Answer:

your answer is A

Explanation:

this is your answer any doubt

Answer 2

Cholesteryl benzoate is an example of such type

Explanation:

• In Normal liquid molecule in isotropic nature is present, whose particle are arranged equally in all direction.

• In liquid crystal anisotropic arrangement is present, whose arrangement is different from different direction

• Substance which possess liquid crystal property contain long or disk shaped molecules which can arrange themselves in diff. way

• There are nematic phase where molecule not get arranged in  layer but end arranged in the same direction.

• In sematic phase molecule get arranged in layer
