Which statement explains why a molecule of ch4 is nonpolar. However to determine if ch4 is polar we consider the molecular geometry.
Chemistry lesson i ve just had.
Is ch4 polar covalent. The electronegativity difference between carbon 2 55 and hydrogen 2 20 atoms in methane ch eq 4 eq is around 0 35 which indicates that the bond is nonpolar covalent moreover the lewis. If you look at the lewis structure for ch4 it appears to be a symmetrical molecule. Yes ch4 is a non polar covalent bond which is not affected by the polarity of water molocules.
It forms a tetrahedral 3d structure and is nonpolar each ion is 109 5 degrees apart in the structure. If c h bond were polar the position of those bonds in 3 dimensional space would cancel out the partial charges from each bond making the whole molecule non polar. The difference in electrostatic potential is also minimal giving an overall nonpolar molecule.
2 the bonds between the atoms in a ch4 molecule are ionic. The electronegativity of carbon and hydrogen is 2 55 and 2 2 respectively which causes the partial charges to be almost zero. Although the four bonds c cl are polar because of the difference in electronegativity of chlorine 3 16 and carbon 2 55 ccl4 is nonpolar because the bond polarity gets canceled with each other due to the symmetrical geometrical structure tetrahedral of the ccl4 molecule.
The compound ch4 is a covalent bond. Interestingly even if c h bonds were polar methane would still be a non polar molecule. 3 the geometric shape of a ch4 molecule distributes the charges symmetrically.
1 the bonds between the atoms in a ch4 molecule are polar. Ccl4 carbon tetrachloride is nonpolar in nature. Ch4 is a nonpolar molecule as it has a symmetric tetrahedral geometrical shape with four identical c h bonds.
Methane is a tetrahedral molecule and so is geometrically symmetric meaning that it looks the same no matter how you rotate it.
