Chiral Carbons print/draw the expanded structure of 4-bromo-4-ethylhept-1-ene. Determine if your molecule contains any chiral carbons. If there are chiral carbons in your molecule, circle or highlight all of them. If your molecule does not contain any chiral carbons explain why none of the carbons are chiral.

Stereoisomers print/draw the expanded structure of 4-bromo-4-ethylhept-1-ene. Calculate the maximum number of possible stereoisomers of the molecule using the following formula. Maximum number of possible stereoisomers = 2n (where n= the number of chiral carbons in your molecule). This calculation does not include E- or Z- isomers for any compounds containing double bonds. Draw the possible stereoisomers of the molecule. Note that E-, Z- isomers of each stereoisomer are also possible and would not be accounted for by the formula above; draw any E- or Z- isomers.

Drawing optical isomers 1. Locate the chiral centre- look for the carbon atom with four different groups attached. 2. Draw one enantiomer in a tetrahedral shape -chlo 1. Loca - put the chiral carbon atom at the centre and the four different groups in a tetrahedral shape around it. Don't try to draw the full structure of each group -it gets confusing, Just use the structural formulas. 3. Draw the mirror image of the enantiomer-put in a mirror line next to the enantiomer and then draw the mirror image of the enantiomer on the other side of it. Example Draw the two enantiomers of 2-hydroxybutanoic acid. The structure of 2-butanoic acid is shown below. 1. Locate the chiral centre 2. Draw one 3.

1. Explain the following - why stearic acid has higher melting point than decanoic acid. - why benzoic acid has higher melting point than stearic acid. - why salicylic acid has higher melting point than benzoic acid. - why octane has a higher melting point than isooctane. - why 2,2,3,3-tetramethylbutane has the highest melting point among the three isomers of C8H18.
For example, alanine is a chiral amino acid that has two enantiomers: (+)-alanine and (-)-alanine. These two are optical isomers. NH2 NH2 4. One of the most important properties of chiral molecules in solution is their effect on plane- polarized light, this effect is called optical activity. -C H 2 COOH HOOC CH When an enantiomer rotates a plane-polarized light in the positive direction or clockwise, it is dextrorotary (+ or d), while for a negative direction or counterclockwise, it is levorotary (- or l) (+)-Alanine (-)-Alanine Alanine is a chiral amino acid that has two enantiomers: (+)-alanine and ()-alanine. These two are optical isomers.
