Note that the C 2 H 4 Lewis dot structure involves sharing more than one pair of electrons. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. In drawing the Lewis structure for C 2 H 2 (also called ethyne) you'll find that you don't have enough valence electrons available to satisfy the octet for each element (if you use only single bonds).
