Concept explainers
Interpretation:
The two molecular characteristics of substances that typically form liquid crystals are to be stated. The relation between the characteristics of substances and function is to be determined.
Concept introduction:
Liquid crystals are the substances that have a crystalline structure and packed with a high degree of order but they can flow like liquids. Liquid crystals phase can arise in two phases as follows:
1. Thermotropic phases: When the liquid crystal arises due to the change in temperature then it is known as thermotropic phases.
2. Lyotropic phases: When the liquid crystal arises due to the change in concentration then it is known as lyotropic phases.

ALEKS 360 for Silberberg Chemistry: The Molecular Nature of Matter and Change
- I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."arrow_forwardSolve the spectroarrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forward
