Formal charges and bonds are shown correctly in this Lewis structure, but lone pairs might be drawn wrong. Add or remove lone pairs to fix the structure. If no corrections need to be made, please check the box below. H H H H :0-C HH C= H =N H CI There are no missing or incorrect lone pairs. P X c+ G 'U 0: C A

Does H4C20 have double bonds? No. Yes, 2 double bonds. Yes, 1 double bon d. Yes, 3 double bonds Yes, 4 double bonds. O0 00

1. Draw a skeleton and make sure the bonds and lone pairs above are added. It is usually best to start with the carbon atoms, then add oxygens, then hydrogens, and fill in with lone pairs ( normally not on carbon ) or multiple bonds if necessary. С — С — С —о 2. Add the hydrogens to the carbon - oxygen skeleton. ннн H С —С | ннн 3. Complete the structure by adding lone pairs (2) to the oxygen atom. ннн H 0-H ннн

Draw skeleton line structure. Be sure your structures show the important difference between the molecules.

Predict the product of this organic reaction: CH3-C-OH + CH₂-OH A →P + H₂O Specifically, in the drawing area below draw the condensed structure of P.
