The molecule that is linear among the given options is CO2.
Explanation:
CO2, or carbon dioxide, is a linear molecule because it consists of two oxygen atoms bonded to a central carbon atom in a straight line, with a bond angle of 180 degrees. This linear shape arises due to the arrangement of the atoms and the nature of the bonding.
Here is a detailed explanation of the molecular geometry of the given options:
a) CO2:
- Carbon dioxide consists of two oxygen atoms double bonded to a central carbon atom.
- The carbon-oxygen bonds are formed by the sharing of electron pairs between the carbon and oxygen atoms.
- The carbon atom is sp hybridized, which means it has two sigma bonds and no lone pairs of electrons.
- As a result, the molecule has a linear shape, with the oxygen atoms on either side of the carbon atom.
- The bond angle between the carbon and oxygen atoms is 180 degrees.
b) NO2:
- Nitrogen dioxide consists of one nitrogen atom double bonded to an oxygen atom, and another oxygen atom single bonded to the nitrogen atom.
- The nitrogen-oxygen bonds are formed by the sharing of electron pairs between the nitrogen and oxygen atoms.
- The nitrogen atom has one lone pair of electrons.
- The molecule has a bent or V-shape, with the nitrogen atom at the apex of the V and the oxygen atoms on either side.
- The bond angle between the nitrogen and oxygen atoms is approximately 134 degrees.
c) SO2:
- Sulfur dioxide consists of one sulfur atom double bonded to an oxygen atom and single bonded to another oxygen atom.
- The sulfur-oxygen bonds are formed by the sharing of electron pairs between the sulfur and oxygen atoms.
- The sulfur atom has one lone pair of electrons.
- The molecule has a bent or V-shape, with the sulfur atom at the apex of the V and the oxygen atoms on either side.
- The bond angle between the sulfur and oxygen atoms is approximately 119 degrees.
d) ClO2:
- Chlorine dioxide consists of one chlorine atom double bonded to an oxygen atom and single bonded to another oxygen atom.
- The chlorine-oxygen bonds are formed by the sharing of electron pairs between the chlorine and oxygen atoms.
- The chlorine atom has two lone pairs of electrons.
- The molecule has a bent or V-shape, with the chlorine atom at the apex of the V and the oxygen atoms on either side.
- The bond angle between the chlorine and oxygen atoms is approximately 117 degrees.
In summary, among the given options, CO2 is the only molecule that is linear, with a bond angle of 180 degrees.

Among the following, the molecule that is linear isa)CO2b)NO2 (1982 - ...
TIPS/Formulae : Hybridisation = 
(V + M – C + A)
where; V = no. of electron in valence shell of central atom M = no. of monovalent atoms, C = charge on cation, A = charge on anion
(i) CO2, H =(4 + 0 – 0 + 0) = 2
∴ sp hybridisation
(ii) SO2, H =(6 + 0 – 0 + 0) = 3
∴ sp2 hybridisation
(iii) NO2 has V shaped structure.
(iv) ClO2 has V shaped structure.
∴ CO2 having sp hybridation has linear shape.
