Choose the correct electron dot structure for the molecule C2H20. The position of the atoms are constant for all answer options but the number of bonds and unshared electrons differ. 1) H- C-CEO: H 2) No bonds. Each H has 1 unpaired electron. Each C has 4 unpaired electrons. The O has 2 unshared electron pairs. 03) H=c- c= :0: H 2) No bonds. Each H has 1 unpaired electron. Each C has 4 unpaired electrons. The O has 2 unshared electron pairs. 3) H C-CEO c H 4) C=C=0 =
