What is a dash wedge structure?
wedge-and-dash (uncountable) (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 is wedge and dash?
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. noun.
Is wedge up or down chair conformation?
Check it out here. Both are on wedges, both are “up” then, and when drawing the chair conformation, one is axial and another equitorial. In the second set, one substituent is “down” and the other is “up”. When labeling the chair, it turns these two specifically to be both equitorial.
How do you identify a wedge and dash?
Think of them as lying in the paper or screen, lined up with one another. wedges – Solid triangular wedges represent chemical bonds and groups that are coming out of the page, toward you. dashes – Dashed triangular shapes represent chemical bonds and groups extending back behind the page.
What is cyclohexane used for?
Most cyclohexane goes into the production of intermediates for nylon, which has a variety of common applications such as clothing, tents and carpets as well as thermoplastics. Cyclohexane is also used as a solvent in chemical and industrial processes and recently has been substituted for benzene in many applications.
What are the two positions of cyclohexane chair?
There are two general positions that a substituent can be in for a chair conformation of cyclohexane: axial and equatorial. Axial substituents are labeled in red below.
Can you draw cyclohexane in the same way?
We see cyclohexane drawn in 2 ways: Both can be used to draw the exact same molecule, but they are simply different ways of representing it. For this majority of this section, we will focus on the chair conformation. Chairs can change conformations through a process called chair flipping, creating 2 conformations for the same chair.
Why are the carbons numbered in cyclohexane axial and Equatorial?
The carbons are also numbered to more easily depict the locations of the carbons before and after the flip. When flipping a ring, a substituent that was axial becomes equatorial and a substituent that was equatorial becomes axial; therefore, the position of the substituent changes.
What does a wedge and Dash bond mean?
$\\begingroup$ So if you drew a wedge in position 1 and a dash in position 2, it would mean that they are on the same plane – either both axial or both equatorial – assuming that the ring was in a chair conformation.
