網頁E. –. Z. notation. E–Z configuration, or the E–Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry. It is an extension of cis – trans isomer notation (which only describes relative stereochemistry) that can be used to describe double bonds having two, three or four ... 網頁R and S refer to Rectus and Sinister, which are Latin for right and left, respectively. Chiral molecules can differ in their chemical properties, but are identical in their physical …
Stereochemistry questions (practice) Khan Academy
網頁Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other. For example, the aldopentoses each contain three chiral centres. Thus, D-ribose is a diastereomer of D-arabinose, D-xylose, and D-lyxose. Epimers are diastereomers that contain more than one chiral center but differ from each other in the … 網頁Stereochemistry Conformation and Mechanism - P. S. Kalsi 2008 Stereochemistry has always occupied a central position and is pivotal to the practice of organic chemistry.
