Question

The type of bond between atoms in a molecule of $C{{O}_{2}}$is:
(A) Hydrogen bond
(B) Ionic bond
(C) Polar covalent bond
(D) Pure covalent bond
(E) Metallic bond

Answer 1

Hint: A chemical bond is a persistent attraction that allows the formation of chemical compounds between atoms, ions, or molecules. Here we need to check the bonds among the following where the polar covalent bond is where a pair of electrons are unequally shared between two atoms as we can see in carbon dioxide.


Complete step by step solution:
When we discuss the physical properties of carbon dioxide it is a colour colourless and odourless gas and it has low solubility in water which gives it an immense biochemical and geochemical importance.
Now let’s discuss its structure and bonds, here in$C{{O}_{2}}$molecule carbon atom undergoes$sp$ hybridization here two$sp$hybridized orbitals of carbon atom overlap with two\[~p\]orbitals of oxygen atoms to make two sigma bonds while other two electrons of the carbon atom are involved in $p\pi -p\pi $bonding with an oxygen atom, this results in its linear shape with no dipole moment.
So, we can also say that the type of bond between atoms in a molecule of $C{{O}{2}}$is a polar covalent bond. Carbon dioxide molecules have two covalent bonds each described as a carbon atom has bonds of four covalent bonds joined with two oxygen atoms.
Hydrogen bonds are weak chemical bonds between electronegative atoms such as oxygen, fluorine or nitrogen (also known as FON) and a hydrogen atom. Ionic bonds involve the electrostatic attraction between oppositely charged ions such as cation and anion. The metallic bond is between the metals in general by sharing of free electrons among positively charged ion structures.

Note: -Polar covalent bond is where a pair of electrons are unequally shared between two atoms such as we can see above in carbon dioxide.
-Pure covalent bond is similar to polar covalent bond but here the bond exists between two atoms with the same electronegativities.
