MHT CET 2026 Chemistry question

What is the proportionality between (I) Bond length and size of atom (II) Bond length and multiplicity of bond respectively?

(A)(I)- direct (II)- inverseCorrect
(B)(I)- direct (II)- direct
(C)(I)-inverse (II)-direct
(D)(I)-inverse (II)-inverse

Answer: (A)

Solution

(I) Bond length is roughly the sum of the covalent radii of the two bonded atoms, so a larger atom gives a longer bond: direct proportionality (e.g. H-F < H-Cl < H-Br < H-I). (II) A higher bond order (multiplicity) pulls the atoms
