The question asks us to fill in two blanks about how bond length and bond strength change when the number of bonds between two atoms decreases.
Think about bond order: higher bond order generally means shorter bond length and stronger bond.
Option 1: 'increases; decreases' predicts that as bonds decrease, length increases and strength decreases. This aligns with the established trend that lower bond order yields longer bonds and weaker bonds, so this option is consistent with the expected behavior.
Option 2: 'increases; increases' would say both length and strength increase when bonds decrease. That contradicts the fundamental idea that decreasing bond order leads to longer, weaker bonds, making this option incorrect.
Option 3: 'decreases; increases' claims that length would shorten while strength would strengthen with fewer bonds. This is opposite to the known pattern, where both lengthening and weakening occur as bond order drops, so this is incorrect.
Option 4: 'decreases; decreases' asserts both length and strength shrink when bonds decrease. Since lower bond order typically produces longer and weaker bonds, this option is also incorrect.
In summary, only the first option matches the established relationship between bond order, bond length, and bond strength when the number of bonds decreases.
