How many isomers does ethene have
WebIn the lewis structure of C 2 H 4, there are only four C-H bonds, one C=C bond and no lone pairs on last shells. There are only single bond between carbon atom and hydrogen atom because hydrogen caannot keep more than two electrons in it's last shell. Therefore, there cannot be more than one stable resonance structure for C 2 H 4. WebThe compound boron trifluoride, BF 3, does not have non-bonding valence electrons and the configuration of its atoms is trigonal.
