trans-cyclooctene is a chiral molecule although there are no chiral centers in it. Explain how trans-cyclooctene is chiral.
Meso compounds, by actual definition, are achiral compounds having chiral diastereomers. However, for our convenience, we think of them as achiral compounds with chiral atoms (stereocenters). This definition makes it easy to identify meso compounds without us having to draw all possible chiral diastereomers. Determine how cis-cycloheptene is a meso compound under the actual definition, but not under the definition that we made for our own convenience.
Draw the three-dimensional structures of the following molecules. Determine which of these has asymmetric carbon and which is chiral despite the lack of an asymmetric carbon.a. (CH3)2C=C=CHBrb. H2C=C=CHBr
Draw the three-dimensional structures of the given molecules. Determine which one has asymmetric carbon and which one has no asymmetric carbon but is still chiral.a. CH3HC=C=CHBrb. BrHC=C=CHBr
Consider the following compounds:
(i) Give the three-dimensional representation of each compound.
(ii) Does any of the compounds contain a chiral carbon atom?
(iii) Does any of the two compounds not contain a chiral center but is chiral?
Draw the three-dimensional structure of the following compound. Does it have asymmetric carbon atom(s)? If it does not have any asymmetric carbons, is it still chiral?
