What type of attraction does the dashed line represent?
A dashed line is used to represent an intermolecular attraction between molecules because these forces are NOT as strong as chemical bonds. One arrangement of ICl molecules that gives rise to a dipole-dipole attraction.
Why are dotted or dashed lines used to indicate hydrogen bonds?
A dotted line indicates that the bond is not a full bond, it is only a partial bond as in a hydrogen bond or a partially formed or broken bond in a transition state.
Which dotted line represents a hydrogen bond?
Hydrogen bonds are represented as H···Y system, where the dots represent the hydrogen bond. Liquids that display hydrogen bonding (such as water) are called associated liquids.
What types of bonds are represented by the dotted lines and the solid lines in the diagram?
What types of bonds are represented by the various lines in the diagram? a. Solid lines are covalent bonds, dotted lines are hydrogen bonds.
What do dashed lines mean in chemistry?
(chemistry) A method of representing the three-dimensional structure of a molecule in which simple lines represent bonds in the plane of the image, wedge-shaped lines represent bonds towards the viewer, and dashed lines represent bonds away from the viewer.
What do the dashed lines represent in the structural formula below?
Dashed lines show atoms and bonds that go into the page, behind the plane, away from you. In the above example, the OH group is going into the plane, while at the same time a hydrogen comes out (wedged).
What does dashed line mean in Lewis structure?
What do the lines between O and H represent?
the solid lines between a hydrogen atom and oxygen atom in the same water molecule c. Both the solid lines and dotted lines represent hydrogen bonding.
What does the dotted line between the water molecules represent quizlet?
Water forms hydrogen bonds with itself. One water molecule can bond with four other water molecules. Represented by a dotted line because hydrogen bonds are weak bonds.
What does A dashed line mean in Lewis structure?
partial bonds
These formulas differ from normal Lewis structures in two ways: 1) dashed lines are used to show partial bonds, and 2) d- and d+ are used to show partial charges (d is the Greek letter “delta” and is commonly used in science and mathematics to indicate a fractional or partial quantity).
What are dashed bonds?
A dashed bond represents a bond moving away from you into the computer screen. A wedge bond represents a bond coming toward you out of the computer screen. Begin by drawing the skeleton of the molecule. To add a wedge bond, click in the lower right of the Bond tool to open the Bonds submenu.
What does a dashed bond mean?
A wedge and dash projection is a drawing, a means of representing a molecule in which three types of lines are used in order to represent the three-dimensional structure: Solid lines to represent bonds that are in the plane of the paper. Dashed lines to represent bonds that extend away from the viewer.
Is a wedge or dash?
Wedges: These are wedge-shaped bonds represents the connected group or atom coming out of the plane towards the viewer. Dashes: Dashed bond represent the connected group or atom behind the paper or away from the viewer.
What do the dashed lines represent between water molecules?
The force of attraction, shown here as a dotted line, is called a hydrogen bond. Each water molecule is hydrogen bonded to four others. The hydrogen bonds that form between water molecules account for some of the essential — and unique — properties of water.
What does the dotted line between the water molecules represent a polar bond a covalent bond a hydrogen bond an electronegative bond?
Where is the negative charge on a water molecule?
oxygen atom
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
What does the dash mean in chemistry?
Using wedge and dash notation, solid lines (sticks) represent chemical bonds in the plane of the surface. Black wedges represent chemical bonds coming toward you, while dashed lines are for bonds that extend back behind the surface.
What does dashed lines mean on molecular formula?
What do dashed lines mean in organic chemistry?
What do the solid/dashed lines on wires mean?
\\$\\begingroup\\$. The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the “wall wart” power supplies. Usually* the wire with the white stripe or the dashed lines carries the “positive” (+) end, while the other, unmarked wire carries the “negative” (-) end.
What type of interaction is depicted by the dashed line?
What type of interaction is depicted by the dashed line? The image is slightly misleading in that the interaction is actually between the second carboxylate oxygen and one of the amine hydrogens. It is in part a hydrogen- bonding interaction, where the carboxylate oxygen is the hydrogen-bond acceptor, and the amine hydrogen is the donor.
Which side of a wire is the positive end?
Usually* the wire with the white stripe or the dashed lines carries the “positive” (+) end, while the other, unmarked wire carries the “negative” (-) end. It doesn’t matter if it is striped or dashed, the presence of any kind of marker is the indicator of the wire being the “positive” end of things, as opposed to the unmarked “negative” wire.
Does it matter if the wire is striped or dashed?
It doesn’t matter if it is striped or dashed, the presence of any kind of marker is the indicator of the wire being the “positive” end of things, as opposed to the unmarked “negative” wire. This kind of convention is used on speaker cables as well, where the wire that is marked in some manner (e.g.
