# How do you determine a group of symmetry?

## How do you determine a group of symmetry?

Assigning Point Groups

1. Determine if the molecule is of high or low symmetry.
2. If not, find the highest order rotation axis, Cn.
3. Determine if the molecule has any C2 axes perpendicular to the principal Cn axis.
4. Determine if the molecule has a horizontal mirror plane (σh) perpendicular to the principal Cn axis.

#### Why is it called Ethanediol?

ethylene glycol, also called ethane-1,2-diol, the simplest member of the glycol family of organic compounds. The name ethylene glycol refers literally to “the glycol made from ethylene.”… Ethylene glycol is a clear, sweet, slightly viscous liquid that boils at 198 °C (388.4 °F).

Is Ethanediol the same as ethylene glycol?

Ethylene glycol (also called 1,2-ethanediol, molecular formula HOCH2CH2OH) is a colourless, oily liquid possessing a sweet taste and mild odour.

What is point symmetry group?

In geometry, a point group is a group of geometric symmetries (isometries) that keep at least one point fixed. Point-group elements can either be rotations (determinant of M = 1) or else reflections, or improper rotations (determinant of M = −1).

## What is the point group of co3?

CO32- – Carbonate C has 4 valence electrons plus 2 for each C=O single bond, and 2 for the charge. Total = 12 electrons, three 4 electron domains. Structure trigonal planar, class AX3. Point group D3h.

### What is the point group of no3?

It has been observed that in going from a nitrate ion (point group n3h sym- metry) to a covalent nitrate (point group Czv symmetry), a lowering of symmetry occurs (9).

#### How many functional groups does Ethanediol have?

A diol is a chemical compound containing two hydroxyl groups (−OH groups). An aliphatic diol is also called a glycol. This pairing of functional groups is pervasive, and many subcategories have been identified. The most common industrial diol is ethylene glycol.

Is Ethanediol soluble in water?
