Question

Arrange the following dicarbon species in order of their bond length :
C2, C2-, C2*2-

Answer 1

Answer:

c2>c2->c2-2

Explanation:

see bond length is inversely proportinal to bond order that is higher the bond order lower will be the bond length and their bond order are as follows

c2=2

c2- = 2.5

c2-2= 3

Answer 2

The order of bond length of the given dicarbon species are: $C_{2}$>${C_{2} ^{-}$>${C_{2} ^{2-}$

We can find out the order of bond length using bond order.

• Bond order is the number of Chemical bonds formed between a pair of atoms. It indicates the stability of a bond.
• Bond order is inversely proportional to the bond length.
• The bond order of $C_{2}$ is 2.
• The bond order of ${C_{2} ^{-}$ is 2.5.
• The bond order of ${C_{2} ^{2-}$ is 3.
