Complete the following structural formula for a neutral molecule

by adding $H$ atoms to complete the valence of each atom. Do not

introduce any double or triple bonds.

Then write the molecular formula in the order CHO.

Complete the following structural formula for a neutral molecule

by adding $H$ atoms to complete the valence of each atom. Do not

introduce any double or triple bonds.

Then complete the Lewis diagram by adding any unshared electron

pairs needed, so that each atom except $H$ has a complete octet.

Write the molecular formula in the order CHO.

Convert the following structural formula to a Lewis diagram by

adding any unshared electron pairs needed, so that each atom

except $H$ has a complete octet.

Include all valence lone pairs in your answer.

If no additional electrons are needed, just click submit.

Should you want to restart the exercise, the drop$-$down

menu labeled $==$ starting points $==$ can be used to

redraw the starting molecule on the sketcher.

The number of unshared pairs in the Lewis diagram $=$

unshared pair$($s$).$
