Although the molecules of CH4 and CH3Cℓ have the same shape, CH4 is non-polar, while CH3Cℓ is polar. Give a reason for the difference in molecular polarity.
The ammonium ion (NH 4 +) and methane (CH 4) have a tetrahedral molecular geometry.

Apr 27, 2011 · When referring to the molecular geometry for sulfur dioxide, the molecular geometry is bent. Note that the bent shape is related to the diffence in electronegativity between sulfur and oxygen (3.5 - 2.5). Since the difference in polarity is greater than zero, SO2 is a polar molecule. The polarity influences the bond angle for the bent geometry.
The molecular structure of the methane molecule, CH 4, is shown with a tetrahedral arrangement of the hydrogen atoms.VSEPR structures like this one are often drawn using the wedge and dash notation, in which solid lines represent bonds in the plane of the page, solid wedges represent bonds coming up out of the plane, and dashed lines represent bonds going down into the plane.
According to VBT: lone pair-lone pair repulsion is more than a bond pair -lone pair repulsion.As the number of lone pair of electrons on central element increases, repulsion between that lone pair of electrons increases and therefore, bond angle decreases. Molecules Bond angle CH4 (no lone pair of electrons) 1090.5 NH3(one lone pair of electrons) 107.50 H2O (two lone pair of electrons) 104.450
