How does the bond length very in dicarbon species
`C_(2),C_(2)^(-),C_(2)^(2-)`

How does the bond length varies in dicarbon species C_(2),C_(2)^(-),C_(2)^(2-)

How would the bond lengths vary in dicarbon species C_2 , C_2^- , C_2^(2-) ?

How would you expect the bond strength to change in the series C_(2) to C_(2)^(-) to C_(2)^(2-) ?

Arrange the following species in order of their in-creasing bond lengths and explain: C_(2),C_(2)^(-) and C_(2)^(2-) .

Compare the C–N bond-length in the following species:

Increasing order of carbon-carbon bond length for the following is : {:(C_(2)H_(4),C_(2)H_(2),C_(6)H_(6),C_(2)H_(6)),((A),"(B)",(C),(D)):}
