Question

Count cases in which the proposed π donation/delocalization gives the named bond partial multiple-bond character in an elementary model: (i) O→B in B(OH)₃, B–O; (ii) N→B in borazine, B–N; (iii) resonance in carbonate, C–O; (iv) resonance in formate, C–O; (v) a pure ethane C–C σ bond attributed to π back donation.

Answer:

4

Solution:

i–iv distribute π density over the named bonds. Ethane lacks the proposed donor/acceptor π system. Count 4.
