What else can I help you with?
What bonded molecules have the lowest melting point?
Covalent molecules which contain only bonds between elements of similar electronegativity. For example: Carbon and hydrogen. They must not contain polar bonds like Oxygen and hydrogen.
Can a molecule be non-polar overall but still contain a polar bonds?
yes
Is CH2CH2CH3 polar or nonpolar?
Bonds between carbon and hydrogen are non-polar.
What molecules possesses polar bonds but is not polar methane sodium chloride carbon dioxide water?
Carbon dioxide
What contain polar bonds P4 H2S NO2 S22?
P4: Nonpolar covalent bonds. H2S: Polar covalent bonds. NO2: Polar covalent bonds. S2Cl2: Nonpolar covalent bonds.
Whether having polar bonds is equivalent to a molecule being polar?
No. Carbon dioxide has polar bonds, but the molecule as a whole is nonpolar because it is symmetric.
Are the bonds in CF4 polar or non polar?
The bonds in CF4 are polar due to the difference in electronegativity between carbon and fluorine. However, the molecule as a whole is nonpolar because the dipole moments of the polar bonds cancel each other out.
Name a non-polar covalent molecule having polar bonds?
carbon dioxide
What nonpolar gases contain polar bonds H2 He O2 N2 or CO2?
Of the gases listed, only CO2 contains polar bonds. The oxygen atom in CO2 is more electronegative than the carbon atoms, creating an asymmetrical distribution of electron density and resulting in a polar molecule.
Is carbon dioxide polar or non- polar?
It is a non-polar molecule. But it has polar covalent bonds between its atoms
Why CCL4 is polar?
Carbon tetrachloride (CCl4) is considered nonpolar because it has a symmetrical tetrahedral shape with four identical covalent bonds between carbon and chlorine atoms. The electronegativity difference between carbon and chlorine is not significant enough to create a polar molecule.
Do polar molecules always contain carbon?
No, polar molecules do not always contain carbon. Polar molecules are characterized by having an uneven distribution of electron density, resulting in a dipole moment, which can occur in various compounds regardless of their elemental composition. Common examples of polar molecules include water (H₂O) and ammonia (NH₃), both of which do not contain carbon. Therefore, while many organic polar molecules do contain carbon, it is not a requirement for a molecule to be polar.
