How do you determine a group of symmetry?
How do you determine a group of symmetry?
Assigning Point Groups
- Determine if the molecule is of high or low symmetry.
- If not, find the highest order rotation axis, Cn.
- Determine if the molecule has any C2 axes perpendicular to the principal Cn axis.
- 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?
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH2OH)2….Ethylene glycol.
