Are dashes and wedges axial or equatorial?

In all cases, a substituent that was marked by a wedge or a dash in a 2-D drawing will remain that way, but in the chair conformation, the wedge might means axial “up” instead of equatorial “up” depending on whether it is a right- or left-handed chair.

How do you determine axial and equatorial?

Axial groups alternate up and down, and are shown “vertical”. Equatorial groups are approximately horizontal, but actually somewhat distorted from that, so that the angle from the axial group is a bit more than a right angle — reflecting the common 109 degree bond angle.

Are wedges up or down?

Wedge: A symbol used to indicate the position of a bond or group relative to the plane of the paper or screen. A solid wedge indicates this bond or group is projecting out towards the viewer. A broken (hashed) wedge indicates this bond or group is receding away from the viewer.

What is axial Equatorial?

Definition of Axial Equatorial The bonds to non-ring atoms are termed axial or equatorial, depending on the bond angle. Bonds to non-ring atoms with angles of about 90° to the ring plane are termed axial. Bonds to non-ring atoms which make only a small angle compared with the plane of the ring are termed equatorial.

What is equatorial or axial?

The carbon bond to the non-ring atoms can be either axial or equatorial. Axial bonds are the bonds that form an 90∘ angle with the ring plane whereas equatorial bonds are the bonds that only make a small angle with the plane.

What are dash or wedge bonds?

Wedge-and-dash definition Filters. (chemistry) A method of representing the three-dimensional structure of a molecule in which solid lines represent bonds in the plane of the image, wedges represent bonds towards the viewer and dashed lines represent bonds away from the viewer.

What is wedge calculation?

Wedge formula: An equation relating the volume of liquid material in a ship’s tank to the dip, ship’s trim, dipping point location and the tank’s dimensions when the ship’s calibration tables cannot be applied.

What is axial and equatorial?

Axial bonds are the bonds that form an 90∘ angle with the ring plane whereas equatorial bonds are the bonds that only make a small angle with the plane. When a corner is pointing up, the axial bonds are drawn straight up, and when the corners are pointing down, the axial bonds are drawn straight down.

What is axial and equatorial position in physics?

Axial line is the line which is passing through the positive and negative charges and the point lies on that line is called the axial point. Equatorial line is the perpendicular line to the line passing through the positive and negative charges and the point lies on that line is known as the equatorial point.

What is equatorial atom?

Equatorial atoms are those atoms that are attached to carbons in the cyclohexane ring and exist at the equator or median of the ring.

What is equatorial bond?

Equatorial: In cyclohexane, a bond which is perpendicular to the axis of the ring (i.e., the bond lies along the equator of the chair), or a group attached by such a bond.

What is a dashed bond?

A dashed line indicates that the bond is extending behind the plane of the drawing surface. A bold-wedged line indicates that the bond is protruding out from the plane of the drawing surface. A solid line indicates that the bond exists in the plane of the drawing surface.

How do you draw a wedge and Dash structure?

Although there is no hard-and-fast rule for drawing a wedge and dash structure, most people find it easiest to visualize the three-dimensional shape of a molecule if the pair of bonds in the same plane as the paper is drawn next to each other, and the bonds in front of and behind the plane are also drawn next to each other…

How can you tell if a chair is axial or equatorial?

You can tell in a chair conformation. I would define equatorial and axial in words but it sounds unnecessarily confusing. Look up chair conformation determine the axial/equatorial positions.

What is the axial and Equitorial position of carbon 1?

Note that the “up” position at carbon 1 is axial while the “up” position at carbon 2 is equitorial. You can go around the ring and keep adding “up” and “down” labels to each carbon this way.

What determines the axial/equatorial positions of a molecule?

Look up chair conformation determine the axial/equatorial positions. If something is “para” in a chair conformation than you will have, say, a CH3 on carbon 1 and the OH on carbon 4.
