The following observations are made about two hypothetical elements A and B: The A?A and B?Bbond lengths in elemental A and B ar
e 2.65 and 1.84 Å, respectively. A and B react to form the binary compound AB2, which has a linear structure (that is ?B?A?B=180? ). Based on these statements, predict the separation between the two B nuclei in a molecule of AB2
The concept of bond length is applied here. Bond length is the distance between the nuclei of atoms in molecules. it can be measured in different ways by X-ray diffraction. It should be noted that the shorter the bond length, the stronger the bond.
Given Bond length of A-A = 2ra, where ra = atomic radius of A
2ra = 2.65 Å
similarly, bond length of B-B = 2rb = 1.84 Å, where rb = atomic radius of B
In AB2, separation between the two nuclei of B = rb + 2ra + rb
