Explanation:<\/h3>\n\n\n\n
To determine if a molecule has a dipole moment, we must consider two factors: the electronegativity differences<\/strong> between atoms and the molecular geometry<\/strong>. A dipole moment arises when there is an uneven distribution of electron density, creating a partial positive and partial negative side in a molecule.<\/p>\n\n\n\n\n
CH (methylidyne radical)<\/strong> consists of one carbon atom and one hydrogen atom. Since carbon is more electronegative than hydrogen, a dipole forms with electrons pulled slightly toward carbon. Therefore, CH is polar<\/strong> and has a dipole moment.<\/li>\n\n\n\n
CHCl<\/strong> contains a carbon atom bonded to hydrogen and chlorine. Chlorine is significantly more electronegative than both carbon and hydrogen, pulling electron density toward itself. The molecular shape does not cancel out this effect, so CHCl has a dipole moment<\/strong> and is polar.<\/li>\n\n\n\n
CH\u2082<\/strong> typically refers to a methylene group. In its simplest form (a neutral CH\u2082), the geometry is bent due to the presence of a lone pair on carbon. This asymmetry and the differing electronegativity between carbon and hydrogen lead to a net dipole moment. Thus, CH\u2082 is polar<\/strong>.<\/li>\n\n\n\n
CH\u2083<\/strong> (methyl radical) has a trigonal planar or slightly pyramidal shape, depending on whether it’s neutral or an ion. The three C\u2013H bonds are identical and symmetrically arranged. Their dipoles cancel each other out, making the molecule nonpolar<\/strong>, so CH\u2083 has no dipole moment<\/strong>.<\/li>\n\n\n\n
CCl<\/strong> involves a carbon and a chlorine atom. Chlorine is more electronegative than carbon, drawing electrons toward itself and creating a dipole. Since it’s a diatomic molecule, there’s no symmetry to cancel the dipole, so CCl is polar<\/strong> and has a dipole moment.<\/li>\n<\/ol>\n\n\n\n
In summary, all molecules listed except CH\u2083 exhibit polarity and possess dipole moments.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
