Use the information in Fig. 3.21 to estimate the bond length of (a) the CO bond in CO2; (b) the CO and CN bonds in urea, OC(NH2)2; (c) the OCl bond in HClO; (d) the NCl bond in NOCl.
There was a similar question on this about how to solve these. However the post said that the answer to b would be 152 because of the single bond between CN, this is also what I got. However the solution manual and back of the book said that the bond would be 142 pm. Why is this?
Thanks so much!
