What does wavy line mean in chemistry?
squiggly line
What is the difference between the solid line and the wavy line?
A solid line indicates that the bond exists in the plane of the drawing surface. A wavy line indicates that the stereochemistry of the bond is unknown.
How do you draw a curved bond in ChemDraw?
Drawing Bézier Curves by Dragging
- Select the Pen tool.
- Point to where you want the beginning of the curve to appear and click.
- Move the cursor to another position and click.
- Position the cursor on one of the points (the “+” in the hand will disappear when you are correctly positioned) and drag to create an arc.
What do the lines mean in organic chemistry?
Remember that each line represents a bond and that the carbons and hydrogens have been omitted. When you look at or draw these structures, the straight lines illustrate atoms and bonds that are in the same plane, the plane of the paper (in this case, computer screen).
What is a bond line formula?
Bond-line structure (bond-line formula, skeletal structure, skeletal formula): A representation of molecular structure in which covalent bonds are represented with one line for each level of bond order. Bond-line structural representation of Taxol (paclitaxel), an anticancer drug.
What do the lines between O and H represent?
What do the lines between O and H in the structural formula of water represent? These lines represent chemical bonds or points of attachment between the atoms. An important group of biological compounds are the saccharides, or more commonly the sugars of carbohydrates.
How do you read a chemical compound?
When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” mono-” indicates one, “di-” indicates two, “tri-” is three, “tetra-” is four, “penta-” is five, and “hexa-” is six, “hepta-” is seven, “octo-” is eight, “nona-” is nine, and “deca” is ten.
How do I find the chemical formula?
Use the Periodic Table. To write chemical formulas, acquaint yourself with chemical symbols, most easily found on the periodic table of elements. The periodic table is a chart of all the known elements, and it often includes both the full name of each element and its symbol, such as H for hydrogen or Cl for chlorine.
What is the correct name for h2o?
Oxidane
What are common chemical formulas?
Formulas and trading names for some common chemicals
| Common used name, trade names | Chemical Name | Chemical Formula |
|---|---|---|
| silver nitrate | silver nitrate | AGNO3 |
| slaked lime | calcium hydroxide | Ca(OH)2 |
| soda ash | hydrated sodium carbonate | Na2CO3 10H2O |
| sodium monoxide | sodium oxide | Na2O |
What is the difference between a molecule name and a chemical formula?
Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. A molecular formula is not a chemical name, and it contains no words. Although a molecular formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula.
What does chemical formula mean?
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
What is the chemical name for n2o3?
Dinitrogen trioxide
What is chemical formula of water?
H2O
What is the chemical formula of oxygen?
O₂
Why is it called H2O?
The scientific name for water is H2O. It is called H2O because it has two atoms of hydrogen (H) and one atom of oxygen (O). There are millions of these molecules in one drop of water. The form water takes depends on the movement of the water molecules.
What are three water properties?
Unique properties of water
- Water is polar.
- Water is an excellent solvent.
- Water has high heat capacity.
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- Water is less dense as a solid than as a liquid.
What are the 3 main characteristics of water?
Physical characteristics of water quality
- Color – pure water is colorless; colored water can indicate pollution.
- Turbidity – pure water is clear and does not absorb light.
- Taste and odor – pure water is always tasteless and odorless.
What are 7 water properties?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends.
