Both CO2 and H2O contain polar covalent ...

Both `CO_2` and `H_2O` contain polar covalent bonds but `CO_2` is nonpolar while `H_2O` is polar because

A

H atom is smaller than C atom

B

`CO_2` is a linear molecule while `H_2O` is an angular molecule

C

`O-H` bond is more polar than `C-O` bond

D

`CO_2` contains multiple bonds while `H_2O` has only single bonds

Text Solution

Verified by Experts

The correct Answer is:
B
In `CO_2`, the polar bonds are arranged in such a way (due to linear shape) that the bond polarities cancel each other while in `H_2O` molecule, the `H-O` bond polarities do not cancel one another (due to angular shape).

  • Assertion : CO_(2) is non - polar while H_(2)O is polar, though both are triatomic. Reason : CO_(2) is linear while H_(2)O is angular.

    A
    Assertion and reason both are correct statements and reason is correct explanation for assertion.
    B
    Assertion and reason both are correct statements but reason is not correct explanation for assertion.
    C
    Assertion is correct statement but reason is wrong statement.
    D
    Assertion is wrong statement but reason is correct statement.

  • Oxygen and sulphur both are3 the member of same group in periodic table but H_2O is liquid while H_2S is gas because

    A
    molecular weight of water is more
    B
    electronegativity of sulphur is more
    C
    `H_2S` is weak acid
    D
    water molecules are having strong hydrogen bonds between them

  • Although both CO_2 and H_2O are triatomic molecules, the shape of the H_2O molecule is bent while that of CO_2 is linear. This is because

    A
    C is less electronegative than H
    B
    C is more electronegative than H
    C
    lone pairs are present on O atom of `H_2O` but not in O atom Of `CO_2`
    D
    lone pairs carrying O is the central atom in `H_2O` but not in `CO_2`
