Question
where the bridging hydrogens are perpendicular to the four terminal hydrogens, which are all coplanar Determine if the following species have permanent dipole moments, Methane, CH_4 Chloromethane, CH_3CI Dichloromethane, CH_2CI_2 Trichloromethane (or chloroform), CHCI_3 Carbon tetrachloride, CCI_4 2,2-Dimethylpropane, CH_3C(CH_3)_2CH_3 Explain why a molecule with a center of inversion cannot have a dipole moment. Unlike methane, bromochlorofluoromethane (CHBrCIF) is chiral. Determine all symmetry elements that are present in CHBrCIF and identify its point group. If the fluorine in this molecule were substituted with a hydrogen atom, what is the point group for the new molecule? Is it chiral?Explanation / Answer
A molecule will have a dipole moment, if it is polar, if the bond dipole moments do not cancel out each other.So linear molecules like CO2 is non polar since it is a linear molecule and has two polar bonds facing in opposite directions with that the molecule itself is not polar.
molecule with center of inversion means it has center of symmetry which for any atom in the molecule there exists another molecule which is form the same distance as that of the other molecule which is identical.
For a molecule with center of inversion acts like the CO2 molecule in which the dipole moments cancel out each other if exists.
