Which molecule out of CO2 and So2 possesses zero dipole moment.explain with reason?
Dipole moment of CO2 molecule is zero,becoz it is linear molecule,whereas SO2 is angular molecule having dipole moment 1.61 D....:)
Does the shape determine the dipole moments?
yes. if the molecule has a linear shape, then it is not polar (most of the time). if the molecule has different shaped elements in it, then it is polar (most of the time). hope i helped! ok so yeah your correct
What nonpolar gases contain polar bonds H2 He O2 N2 or CO2?
CO2 has ploar carbon-oxygen bond, but the molecule is non-polar as the dipole moment cancel off.
Which is dipole molecule hcl cl2 ccl4 CO2?
hcl
Which of the following molecules has a polar covalent bond?
H2 has non polar covalent bond. H2O and HCl are polar covalent. LiI-- thats ionic- so is not molecular under normal conditions- if a molecule were formed in gas phase then that would be polar too.

Why does CO2 have a permanent dipole-dipole interaction?
Carbonate (CO3 2-) is trigonal planar with a central C and three O's 120 degrees from each other (D3h symmetry). All the O's have the same electron density because of resonance. This gives carbonate no dipole.

What is a active gas?
Absorption of energy from IR radiation can only occur when the wavelength of radiation and the wavelength of the bond vibration match. If a molecule has symmetry...for example no dipole, we say it is IR inactive. CO2 has no dipole....this would be an IR inactive gas...Cl2 as well. A gas that has a dipole would be IR active. Propene would be a nice example of an IR active gas.It possesses a dipole. One would see a signal around 1650.A:CO2 has no permanent dipole. However, when CO2 undergoes a bending vibration, its dipole moment changes from zero to some non-zero value. This vibration produces a change in dipole moment and is therefore IR active.

Why do greenhouse gases trap infrared radiation but not homonuclear molecules?
1) Absorption of IR radiation depends on the dipole moment of a molecule (which might be considered the tension on the shared electrons within the molecule). 2) In a homonuclear molecule (such as O2), the identical nuclei exert an identical pull on the shared electrons. The dipole moment is zero, and can interact with radiation of zero frequency and zero wavelength. Such radiation does not exist. 3) In a heteronuclear molecule such as water, the differing nuclei of oxygen and hydrogen exert an unequal pull on the shared electrons. This produces a non-zero dipole moment which is capable of interacting with infrared radiation, raising the molecule to a higher energy level. 4) Carbon dioxide (CO2) is a particular case. The oxygen atoms are at exactly opposite sides of the carbon. Although each side has a dipole moment, since the molecule is symmetrical it tends to cancel out. However, there is the possibility of movement of nuclei within the molecule. If the movement is symmetrical, there is no dipole moment. If the movement is asymmetrical, a dipole moment is temporarily produced. If there is infrared radiation present in the right orientation, interaction is possible. Therefore carbon dioxide is a fairly weak greenhouse gas. However, since it is being continually introduced into the atmosphere by human activity, its effect is being raised continually as well.
Why CO2 it is in gas status?
Because its molecule is linear O=C=O having no dipole moment so its molecules do not attract each other to form a liquid or solid at room temperature and hence it exists in gaseous form.
