c2cl4 and c2h2
Among the molecules listed, HF and NF3 have polar bonds due to differences in electronegativity between the bonded atoms. ICl3, SF4, and BF3 are nonpolar because the bond dipoles cancel out in these molecules, resulting in a symmetrical distribution of charge.
Molecules that permit free rotation about the carbon-carbon bond include C2H2 (acetylene) and C2H4 (ethylene) due to the presence of a triple bond and a double bond respectively. On the other hand, C2Cl4 (tetrachloroethylene) and C2H5Cl (chloroethane) do not permit free rotation about the carbon-carbon bond due to the presence of chlorine atoms or a bulky ethyl group that restrict rotation.
C2H2 (Ethyne or Acetylene) is nonpolar because the molecule has a linear geometry with symmetric electronegativity, resulting in an equal distribution of charge and no net dipole moment.
CH2 does not exist as a molecule. There are, however, C2H2 and CH4, both of which are nonpolar.
The balanced equation for the complete oxidation of acetylene (C2H2) burning in air is: 2C2H2 + 5O2 -> 4CO2 + 2H2O. This equation shows that two molecules of acetylene react with five molecules of oxygen to produce four molecules of carbon dioxide and two molecules of water.
C2H2 and CO2 are linear molecules and are non polar.

C2H2 (acetylene) has the lowest boiling point among the molecules listed. This is because it is a small, nonpolar molecule with weak intermolecular forces, which results in low boiling point.
C2H2 (Ethyne or Acetylene) is nonpolar because the molecule has a linear geometry with symmetric electronegativity, resulting in an equal distribution of charge and no net dipole moment.
The chemical equation for the reaction of acetylene (C2H2) with two molecules of Br2 (bromine) is: C2H2 + 2Br2 → C2H2Br4
In nonpolar molecules, the main type of bond present is usually nonpolar covalent bonds. These bonds occur when atoms share electrons equally, resulting in a balanced distribution of charge and a lack of overall polarity in the molecule. Van der Waals forces may also contribute to interactions between nonpolar molecules.
H2, CH4, Cl2, C2H2, CO2, O2 were all non polar atoms because they all were not lone pairs (meaning that there were no one dots). Also don't write this down but look at all the bonds. They all have 2 or 4 and not 3 or 5. For example: Cl2 and not Cl3.
C2H2 (acetylene) is a nonpolar molecule. This is because the molecule is linear with a symmetrical distribution of the carbon-hydrogen bonds, leading to a net dipole moment of zero.
No, like other hydrocarbons C2H2 is nonpolar. So it is dominated primarily by London dispersion forces.
CH2 does not exist as a molecule. There are, however, C2H2 and CH4, both of which are nonpolar.
