Question 27

Which of the following statement are correct about $C O_{3}^{- 2}$ ?

(a) The hybridisation of central atom is $s p^{3}$

(b) Its resonance structure has one C - O single bond and two C = 0 double bonds

(c) The average formal charge on each oxygen atom is 0.67 units

(d) All C - O bond lengths are equal

Q. Why resonating structures lose their individual identity?

Q. Cyclobutadiene (below) is like benzene in that it has alternating single and double bonds in a ring. However, its bonds are not same length, double bonds being shorter than the single bonds; the molecule is rectangular, not square. Explain why it would be incorrect to write resonance structures as shown.

In the thiocyanate ion,

S C N^{-}

, three resonance structures are consistent with the electron-dot method. Structure A has only one negative formal charge on the nitrogen atom, the most electron negative atom in the ion. Structure B has a single negative charge on the

S

, which is less electronegative than

N

. Structure C has charges of

- 2

N

+ 1

on S, consistent with the relative electronegativities of the atom s but with a larger charger and greater charge separation than the first.
