Answer» hey MATE your answer is here ⬇️ ⬇️⬇️⬇️ in simple word ibsay that, bond order and bond enthalpy both are inversely proptional to bond length Explanation: Higher the bond energy the 'stronger' the bond is between the two atoms, and the distance between them ( i.e.bond length) is smaller. Bond order represents the number of bonds between two atoms/elements. So bond length decreases with MULTIPLICITY of bonds between two elements and INCREASES with LESSER amounts of bonds, the LARGER the Bond Order, the stronger the bond, and shorter the distance

hey MATE your answer is here ⬇️ ⬇️⬇️⬇️

in simple word ibsay that,

bond order and bond enthalpy both are inversely proptional to bond length

Explanation:

Higher the bond energy the 'stronger' the bond is between the two atoms, and the distance between them ( i.e.bond length) is smaller.

Bond order represents the number of bonds between two atoms/elements. So bond length decreases with MULTIPLICITY of bonds between two elements and INCREASES with LESSER amounts of bonds, the LARGER the Bond Order, the stronger the bond, and shorter the distance
