Which of these bonds to carbon would you expect to be relatively reactive: C - H, C- C, C - I, C = O, C - Li ? Explain.

Electronegativity is the ability of an atom to attract the shared pair of electrons towards itself. If the two atoms of a bond are of equal electronegativity then the electrons are equally shared. If the electronegativity difference is greater, then the bond becomes polar and Carbon becomes reactive.

Now,

In case of C-H bond , the electronegativity difference of the two atoms is 0.4 which means that electron are equally shared, Hence , C-H bond is not reactive.
In case of C-C bond, the atoms are identical, electronegativity difference is 0 , Hence, C-C bond is not reactive.
In case of C-I bond , the electronegativity difference of two atoms is greater. The bonds become polar and carbon becomes reactive.
In case of C = O bond, the electronegativity difference is 0.49 which means C = O bond is non polar and the carbon is slightly reactive.
In case of C-Li bond, the electronegativity difference is greater. The bond becomes polar and the carbon becomes reactive.

Hence,

C-I bond and C-Li bond are reactive whereas C = O is slightly reactive as compared to these two.

Thus from the above conclusion we can say that, C-I bond and C-Li bond are reactive whereas C = O is slightly reactive.
