The correct order of increasing bond angles in the following species is
- $Cl_2O < ClO_2 < ClO_2^- $
- $ClO_2 < Cl_2O < ClO_2^- $
- $Cl_2O < ClO_2^- < ClO_2$
- $ClO_2^- < Cl_2O < ClO_2 $
The Correct Option is C
Approach Solution - 1
The correct order of increasing bond angles in the following species is
\(Cl_2O < ClO_2^- < ClO_2\)
This is because In \(ClO _{2}^{-}\)there are two lone pairs of electrons that repel each other due to which two oxygen atoms come closer leading to a decrease in bond angle. Therefore the bond angle in \(ClO _{2}^{-}\)is less than \(118^{\circ}\) which is the bond angle in \(ClO _{2}\) which has less number of electrons on chlorine.

Approach Solution -2
The correct answer Option C) \(Cl_2O < ClO_2^- < ClO_2\)
Real Life Applications
- The shape of the molecules can be predicted using the bond angles, thus will help in understanding the properties of molecules.
- The bond angle understanding can be used in pharmaceutical companies.
- This will help in designing new drugs and medicines. An entire new material can be made using material science if proper knowledge of bond angle is present.
Question can also be asked as
- How do the bond angles in the following species compare?
- Which species has the smallest bond angle?
- Which species has the largest bond angle?
Approach Solution -3
The correct answer Option C) \(Cl_2O < ClO_2^- < ClO_2\)
The characterization of covalent bonds is done on the basis of bond parameters. The parameters are bond angle, bond enthalpy, length, etc.
Bond length
The bond distance is the bond length. It is the separation length of the bonded atom. There is a direct relation between the radius of the atom and bond length.
Bond angle
The bond angle is the angle between two covalent bonds. It is the geometry angle. The geometry of the molecule can be determined with the help of bond angle and bond length.
Bond order
The electron pairs between the two atoms are called the bond order. The bond order of a single bond is 1. The bond order of double bond is 2 and that of triple bond is 3.

Chlorine
A chemical element with the symbol Cl and the atomic number 17 is ‘Chlorine’. It is the second-lightest of the halogens that appears between fluorine and bromine in the periodic table and its properties are median between them. At room temperature, it is a yellow-green gas. Also, it has two stable isotopes, 35Cl and 37Cl. These are the only two natural isotopes occurring in quantity, with 35Cl making up 76% of natural chlorine and 37Cl making up the remaining 24%.
Applications of Chlorine:
- In water purification, disinfectants, bleach, and mustard gas, chlorine is an important chemical.
- Also, it is widely used in the manufacture of many products and items directly or indirectly, i.e. in paper product production, antiseptic, dyestuffs, food, plastics, medicines, insecticides, paints, petroleum products, textiles, solvents, and many other consumer products.
- It is also used to kill bacteria or to disinfect drinking water supplies.
- Chlorine is mixed up in beaching wood pulp for papermaking, also bleach is used industrially to remove ink from recycled paper.
- Chlorine often set forth many desired properties in an organic compound when it is substituted for hydrogen (synthetic rubber), so it is widely used in organic chemistry, in the production of chlorates, carbon tetrachloride, chloroform, and the bromine extraction.
