In alkanes, the positions of side chains or alkyl substituents are indicated by lowest numeral places before prefix.
In order to assign absolute configuration of R and S, Cahn−Ingold−Prelog rules are used and the first step is to assign the priority order on the basis of
The Fischer projection is written along with the priorities assigned and groups are interchangedbetween adjacent places so as to obtain lowest priority group at the bottom or lowest priority.
If the groups now are arranged are read from highest towards least in clockwise fashion the R is assigned to the stereocenter, if the rotation is anticlockwise the S is assigned at the configuration.

- Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х аarrow_forwardPredict the major products of this organic reaction.

Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area.
