QJEEM23Chbdb0: JEE Main 2023 Chemistry - Class 11 JEEM23Chbdb0 Solution: The number of bent-shaped molecule/s from the following is…

The number of bent-shaped molecule/s from the following is __________

N 3−_3^- , NO 2−_2^- , I 3−_3^- , O 3_3 , SO 2_2

Step-by-Step Verified Solution

A bent-shaped molecule has a molecular geometry with a central atom bonded to two other atoms and one or two pairs of non-bonding electrons. The VSEPR (Valence Shell Electron Pair Repulsion) theory helps us predict the shapes of molecules.

Let's consider the given molecules:

  1. N 3−_3^- : The azide ion has a linear shape, not bent. The nitrogen in the middle is connected to two other nitrogens and there are no lone pairs on the central atom.


  2. NO 2−_2^- : The nitrite ion has a bent shape. The central nitrogen atom is connected to two oxygen atoms and has one lone pair of electrons, giving it a bent geometry.


  3. I 3−_3^- : The triiodide ion has a linear shape, not bent. The central iodine atom is connected to two other iodine atoms and there are no lone pairs on the central atom.


  4. O 3_3 : Ozone has a bent shape. The central oxygen atom is connected to two other oxygen atoms and has one lone pair of electrons, giving it a bent geometry.


  5. SO 2_2 : Sulfur dioxide has a bent shape. The central sulfur atom is connected to two oxygen atoms and has one lone pair of electrons, giving it a bent geometry.

Therefore, there are 3 bent-shaped molecules: NO 2−_2^- , O 3_3 , and SO 2_2 .
