Dicarbon monoxide, c2o, is found in dust clouds in space. analysis of it shows that the sequence of atoms in this molecule is c–c–o. all bonds are double bonds and there are no unpaired electrons. how many lone pairs of electrons are present in a molecule of c2o?

Carbon dioxide has 4 lone pairs of electrons. During bonding, the bonds accounts for 8 electrons of the 16 valence electrons the molecule has. The remaining 8 valence electrons will be placed as lone pairs, two on each oxygen atom. As a result carbon dioxide molecule has a total 4  lone pairs of electrons. Dicarbon monoxide is a molecule that contains two carbon atoms and one oxygen atom.  A lone pair refers to a pair of valence electrons that are not shared with another atom and is some times called a non-bonding pair. Lone pairs are found in the outermost electron shell of atoms.
