Interpretation:
The three-dimensional formula with the help of dashes and wedges for bonds is to be drawn. All unshared electron pairs and hydrogen bonds are to be shown. The
Concept introduction:
The molecules that are nonsuperimposable or not identical with their mirror images are known as chiral molecules.
A pair of two mirror images that are nonidentical is known as enantiomers, which are optically active.
The stereoisomers that are nonsuperimposable on each other and not mirror images of each other are known as diastereomers.
The achiral compounds in which plane of symmetry is present internally and consists of chiral centres are known as meso compounds, but they are optically inactive.
Each center is analyzed separately, if the compound contains more than one chirality center.
The designation of each carbon is determined by using the numbers.
When the order of progression from the group of highest priority to that of the next highest priority is clockwise, it is said to be the
When the order of progression from the group of highest priority to that of the next highest priority is anticlockwise, then it is said to be the

- Q2: If you think you know your definitions, try this difficult problem. (a) Draw all the stereoisomers of 2,3.4-tribromonentane, (Using Fischer projections may helpful.) You should find two meso structures and one pair of enantiomers. (b) Star (*) the asymmetric carbon atoms, and label each as (R) or (S). (c) In the meso structures, show how C3 is pot asymmetric, nor is it a chiral center, Yetn stereocenter. (d) In the enantiomers, show how C3 is not a stereocenter.arrow_forwardShown are three molecules A, B and C; only one of the molecules is chiral. Identify the chiral molecule (putting a circle around it suffices) and assign its absolute chirality. Draw the opposite enantiomer of the molecule that you have identified as chiral. A Barrow_forwardConstruct a model in which a tetrahedral carbon atom has four different colored model atoms attached to it- red, green, orange and white representing 4 different atoms attached to the central atom. a) Does the atom have a plane of symmetry? why or why not? b) Now replace the green atom in your model with a second orange atom. Now two of the groups attached to the carbon atom are identical. Does the model now have a plane of symmetry? Describe it. c)A carbon atom has four different groups attached to the stereogenic center. Draw structural formulas for the following compound and mark stereogenic centers with as asterisk: 1-bromobutane, 2-bromobutane, 1,2-dibromobutane, 1,4-dibromobutane, 2,3-dibromobutane.arrow_forward
