Relate single, double and triple bonds to one, two and three shared electron pairs, and explain why a higher bond order gives a shorter and stronger bond, using bond enthalpy and bond length data from the data booklet.
(i) For the carbonate ion, draw its Lewis formula. (ii) Write the chemical formula of ammonium carbonate. (iii) State why all three C–O bonds in the carbonate ion are identical. (iv) Using section 11 of the data booklet, predict the length of the C–O bonds in…
