Question

Which one of the following arrangements
represents the increasing bond length of
the given species?
A NO+ < NO< NO- < 02-
B O2-< NO- <NO < NO+
с NO- <O2-, < NO < NO+
D NO < NO+< O2-, < NO-​

Answer 1

Answer:

A . NO+ < NO < NO- < O2

Explanation:

bond length is inversely proportional to bond order

Answer 2

the increasing bond length of (A ) NO+ < NO< NO- < 02-

Explanation:

1.In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.

2.The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length.

3.Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
