Answer 1

CFCL3,HAVE PERMANENT DIPOLE MOMENT PRESENT

Answer 2

Answer:

$O_{3}$ , CH and CIF have a permanent dipole.

Step-by-step explanation:

$O_{3}$ =Have unsymmetrical structure so it has a permanent dipole moment.

CO = the dipole moment of CO is low i.e. 0.122D. The resonance which suggests a dipole in the direction of carbon and inductive effects which suggests a dipole facing oxygen is not a comparable factor associated with CO.

$CO_{2}$ = Molecules with mirror symmetry like oxygen, nitrogen, carbon dioxide, and carbon tetra chloride have no permanent dipole moments.if there is no permanent dipole moment, it is possible to induce a dipole moment by the application of an external electric field.

N, O  = nitrogen, and oxygen have no permanent dipole moments.If there is no permanent dipole moment, it is possible to induce a dipole moment by the application of an external electric field.

$XeF_{2}$ = The XeF2 dipole moment  is zero

NO = The dielectric constant of nitric oxide is measured over a wide range of temperatures and used to calculate the dipole moment of the molecule, which is found to be less than 0.1×10—18, and so small as to be indistinguishable from zero.

CH = the bond dipole moments do not cancel one another, and the result is a molecule that has a dipole moment. The hydrogen molecule is less electronegative than carbon and so is slightly positive.

CFCL3= No dipole. CHCL3 the charges cancel as they are in all three 'arms' of the molecule. Overall no polarity.

CIF = ClF is a linear molecule. F is more electron negative than Cl, so the direction of dipole moment is from Cl to F and the molecule is polar.
