This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another. The existence of these molecules is determined by concept known as chirality. The word “chiral” was derived from the Greek word for hand, because our hands are good example of chirality ...

When you look at it that way, they're clearly different, and should be treated as such. – wes3449. sign in and sign out software https://principlemed.net

7.2: Naming chiral centers: the R and S system

Web5.3 Designating R vs. S Configuration / Four Steps • “R” or “S” is assigned to a chiral center using a stepwise procedure 1. Using atomic numbers, prioritize the four groups attached to the chiral center (1, 2, 3 and 4) 2. Arrange the molecule in space so the lowest priority group faces away from you 3. WebIn most cases, the easiest way to decide whether a molecule is chiral or achiral is to look for one or more stereocenters - with a few rare exceptions, the general rule is that molecules with at least one stereocenter are chiral, and molecules with no stereocenters are achiral.

These centers can be described as R or S, meaning the molecule can have either “right-handedness” or “left-handedness”. Label the groups by priority 1-4, with the highest priority being 1. If two atoms are the same, look to the next connected atom.

WebIn stereochemistry, a stereocenter of a molecule is an atom (center), axis or plane that is the focus of stereoisomerism; that is, when having at least three different groups bound to the stereocenter, interchanging any two different groups creates a new stereoisomer. Stereocenters are also referred to as stereogenic centers..

WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.
