# Problem: Supply a structural formula for the major organic product(s) when the product(s) is(are) not given; if no reaction occurs, write N.R. If the major product is a mixture of stereoisomers (such as a pair of enantiomers or a pair of diastereomers), give a structural formula for each of the stereoisomers in the mixture.
