Ammonia is polar because it's shape is SYMMETRICAL.I hope this helps you in what you are looking for.
All trigonal pyramids are polar. As they have non-symmetrical shape, therefore uneven pull; polar.
The shape is trigonal pyramidal Polarity is non-polar
To create beautiful decorations using paper towel flowers, you can start by cutting paper towels into flower shapes and coloring them with watercolor paints. Then, twist and shape the paper towel petals to create a realistic flower look. Finally, arrange the paper towel flowers in a vase or use them to embellish gifts or cards for a lovely touch.
Yes, the Cl-F bonds are polar and the resultant bond dipoles do not cancel out because of the shape of the molecule, Bent T shape.

BeF2 is non-polar as it is (strangely) covalent in nature and as such, the molecule has a linear shape which produces a non-polar molecule.
Yes, it is.A compound is non-polar if there is no net dipole.This can be achieved through one of the following:It has no polar bonds orThe shape of the molecule is such that the dipoles created cancel out.This means that a compound with polar bonds must have a symmetrical shape in order for it to be non-polar.Take CCl4 (carbon tetrachloride). The C-Cl bond is polar, however, the shape of the molecule is tetrahedral - it is symmetrical and so dipoles cancel out. Therefore, it is non-polar.
when the molecule contains polar bonds
I2 is non-polar because it has a symmetrical linear shape, with the same atoms on both ends creating a balanced distribution of charge.
if molecular shape is symmatrical then its non-polar but if it is non symmatrical then its polar.
Answer 1:The presence of polar bonds Answer 2:The shape of the molecule Apex
