Denison University Chemistry Worksheet
1. Interpret why the “third carbon” of 3-ethylpentane does not keep any chiral carbons.
2. Why are R-2-methylbutane and S-2-methylbutane enantiomers?
3. Briefly draw the steps to state if an isomer is “R” or “S”. Be trusting to conceive the basic pre-eminence rules in your repartee.
4. How abundant completion stereoisomers succeed a atom keep if it has 3 stereocenters (3 chiral carbons)? List all of the stereoisomer combinations (e.g. – R, R, R)?
5. 2-bromo-3-chloropentane has two stereocenters; for-this-reason, it has disgusting stereoisomers. Give the names of a set of diastereomers.
6. True/False (briefly interpret): For Fischer projections, clockwise revolution frequently indicates an “R” stereocenter.
