Question

Bond length decreases with:
(a) decrease in size of the atom
(b) increase in the number of bonds between the atoms
(c) decrease in bond order
(d) decrease in the number of bonds between the atoms​

Answer 1

Answer:

b.............................

Answer 2

Answer:

Bond length depends on the size of the atoms and the multiplicity of bonds. As the atomic size increases, the bond length increases. As the multiplicity of bond (also known as bond order) increases, bond length decreases.

Oxidation number of central atom and the percentage s-character in the orbitals used in making the bond also affects the bond length. Higher the positive charge on atom, smaller is the bond length. Greater the s character, smaller is the bond length.
