WebCrystal structure studies have shown that in solid urea, both nitrogen atoms are identical. Bond length measurements [6] in urea give the C-N distance as 1.37A o, while, in aliphatic amines the C-N bond length is 1.47A o. This indicates that the C-N bond in urea has some double bond character (about 28%). WebThe electron configuration of an oxygen atom [He] 2 s2 2 p4 suggests that neutral oxygen atoms can achieve an octet of valence electrons by sharing two pairs of electrons to form an O=O double bond, as shown in the figure below. According to this Lewis structure, all of the electrons in the O 2 molecule are paired.
