Pauling's relation gives ∣χA−χB∣=0.102Δ, where Δ (in kJ mol−1) is the extra bond energy of A-B over the geometric mean of the A-A and B-B bond energies. The bond dissociation energies are: A-A90kJ mol−1, B-B360kJ mol−1, A-B318kJ mol−1. In the AB molecule the B atom carries the partial negative charge, and χB=3.2. Find 10χA. The answer is an integer; round to the nearest whole number.
