Answer

The lewis structure is shown in the picture.

Work Step by Step

1) Draw the structure in the sequence shown in the formula. 2) Count the number of valence electrons involved in the bonding, which is 36e. There should be 50e. Make a one more bond between C and C, and C and O. Now there are 42e. 3) Since O,C, H have already made the max bonds possible, place the remaining electrons as lone pairs, two on each O. 4) Now count the valence electrons, it should be 50e.
