|
enantiomers |
are mirror images |
|
structural isomers |
differ in the covalent bond relationship among their atoms |
|
this pair of molecules are |
not isomers because they have different molecular formuls |

|
which of these is a carboxyl group? |
f |
|
which of these functional groups is characteristic of alcohol? |
