The type of bond between atoms in a molecule of CO2 (electronegativity difference = ~1)
a. hydrogen bond
b. ionic bond
c. polar covalent bond
d. pure covalent bond
e. metallic bond
Answer (2)
carbon dioxide, or C O 2 , is a pure covalent bond.
pure - it's non-polar, because it's a linear & symmetrical bond.
covalent - covalence is when 2 electrons are shared by a pair of atoms. in the case of carbon dioxide, it's three atoms with an oxygen atom on the right, an oxygen atom on the left, and a carbon atom smack in the middle. 2 of carbon's extra electrons are shared with the right oxygen, and 2 other extra atoms are shared with with left oxygen.
In carbon dioxide (CO₂), the type of bond present between the carbon and oxygen atoms is known as a polar covalent bond, characterized by an unequal sharing of electrons due to the higher electronegativity of oxygen. Despite each bond being polar, the linear geometry of CO₂ causes the polarities to cancel, making the overall molecule nonpolar. Thus, the correct answer is option c: polar covalent bond.
