Question

The bond length of Cl2 molecule is
a) 0.74
b) 1.44
c) 1.98
d) 2.28

Answer 1

The bond length of Cl2 molecule is :1.98 A°


⇒Bond length is the distance between the nuclei of the atoms in a molecule .

⇒Bond length is equal to sum of covalent radii of the two atoms that are bonded.

⇒Units of Bond length are A or cm or m.

⇒As the number of bonds between two atom increases the bond length increases.

∴ Bond        Bond length
  Cl-Cl             1.98 A°

Answer 2

The bond length of Cl2 molecule is :1.98 A°

⇒Bond length is the distance between the nuclei of the atoms in a molecule .

⇒Bond length is equal to sum of covalent radii of the two atoms that are bonded.

⇒Units of Bond length are A or cm or m.

⇒As the number of bonds between two atom increases the bond length increases.

∴ Bond        Bond length

  Cl-Cl             1.98 A°
