Here it says which of the following statements best describes the relationship between bond length and bond strength for a series of compounds involving bonds between the same 2 atoms. All right, the greater the bond strength, the longer the bond. Now we know there's an inverse relationship between bond strength and bond length.
If one goes up, the other one has to come down. So the bond would have to get shorter, not longer. This one here is the correct answer. The greater the bond strength and the shorter the bond will get. Here, bond strength and bond length are not related. That's not true. They're inversely proportional.
The relationship between bond length and bond strength depends on other factors. No. The only correct answer here would have to be option B.
