is nh bond polar or nonpolar?

In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).

C2Br2 : If we look at this structure then there is symmetry in it. Due to this symmetry dipole moments of 4 C-Br bond is cancelled and resultant dipole moment of the molecule is 0. Therefore molecule is non polar.

(If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.) If there are no polar bonds, the molecule is nonpolar. If the molecule has polar bonds, move on to Step 3.

HCN is polar with the hydrogen end somewhat positive and the nitrogen end somewhat negative.

Polar covalent bond or partially ionic covalent bond. HF is a polar molecule in which H-F bond is a polar covalent bond due to unequal sharing of electrons between more electronegative F and less electronegative H atoms.

A molecule will be polar if it has a net dipole. Both the C-H and the C-N bonds are polar. Nitrogen is more electronegative than carbon which is more electronegative than hydrogen.

Phosphine is an example of a polar molecule with non-polar bonds. It has the formula PH3. ... The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution and that's why the molecule is polar even though it has non-polar bonds.

CH4 is non-polar. The electronegativity difference between carbon and hydrogen is only 0.4, so the C-H bonds are only slightly polar.

NH3 is highly soluble in water. The lone pair of electrons on the nitrogen atom makes ammonia a polar substance. Water is a polar substance too....

Taking the example of BCl3 and NH3, you have non-polar BCl3 (because of its flat geometry and symmetrical distribution of electrons) forming a polar non-covalent bond with the NH3 molecule (polar because of its tetrahedral geometry with a lone-pair of electrons attached to the nitrogen).

NaHCO3 (sodium bicarbonate) is neither polar nor non-polar in its pure form because it is not a covalent compound. It is an ionic compound. Polar can also be used to describe if something will dissolve in a polar solvent like water. NaHCO3 is a soluble ionic compound, so it would be considered polar in this case.

If the bonds are ionic, the atoms can't be considered polar or non-polar. Examine each of the atomic elements contained within the molecule. Generally, bonds between two of the same atoms, such as nitrogen (N2) or oxygen (O2) have an even distribution of electrons, making the atoms non-polar.

Although a symmetrical molecule is always non-polar even if the polar bonds are present in the molecule. In CF4 molecule there are four C-F bonds in tetrahedral geometry. Since all four bonds are same therefore they will cancel the polarity of each other and makes the CF4 molecule non-polar.

In N2, the atoms bonded to each other are the same and hence have the same electronegativity. As such, the electrons shared are not preferentially drawn to either. This results in the formation of a non-polar bond in N2. In a polar covalent bond, the more electronegative atom gets the δ + (delta +) symbol.

Polarity of PBr5 Due to its trigonal bipyramidal geometry, each bond is symmetrically opposed to other ones. As a result of this geometry and arrangement of electrons, the net dipole moment of the molecule is zero. Hence there is no polarity observed in the compound and PBr5 is thus nonpolar.

O-H bond is non-polar. NH4Cl: all the bonds are polar . HCN: Both the C-H and the C-N bonds are polar .

NH3 or commonly known as Ammonia is held together with covalent bonds, not ionic. This means that they're sharing electron pairs. The molecule is polarized with a slight positive charge on the H3 side and conversely a slight negative charge on the Nitrogen side.
