A polar bond occurs when there is an unequal sharing of electrons between atoms, resulting in a slight positive and negative charge. A nonpolar bond occurs when there is an equal sharing of electrons, leading to no charge separation.
Both actually. It just depends on the electro-negativity of the atoms bonded together. If both have the same electro-negativity, it is a nonpolar covalent bond. Otherwise, you have a polar covalent bond.
The bond between oxygen and hydrogen is considered polar because of the difference in electronegativity between the two atoms. Oxygen, being more electronegative, will attract the shared electrons more strongly, creating a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atom.
CH3Br is a nonpolar molecule. Although the C-Br bond is polar due to the electronegativity difference between carbon and bromine, the overall molecule is nonpolar because of its symmetrical tetrahedral molecular geometry.
The electronegativity of oxygen is 3.44 and for fluorine it is 3.98. The difference in electronegativities is 0.54, so the bond between fluorine and oxygen is polar covalent.
HBF2 is polar. This is because the bond between hydrogen and fluorine creates a dipole moment due to the electronegativity difference between the two elements.

No. It is nonpolar. The difference in electronegativity is 0.38, which means the H-S bond is nonpolar.

Yes, Br2 contains a nonpolar covalent bond. The electronegativity difference between bromine atoms is very small (Br: 2.96), so the bond is nonpolar.
In a polar bond, there is an unequal sharing of electrons between atoms due to differences in electronegativity, resulting in a partial positive and partial negative charge. This creates a dipole moment. In a nonpolar bond, there is equal sharing of electrons between atoms resulting in no dipole moment.
A polar covalent bond is a bond between two nonmetal atoms with different electronegativity's. Technically, only a bond between identical nonmetal atoms would be truly nonpolar, but in most cases a threshold is set for electronegativity difference to be considered polar.
Predicting if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table involves comparing their electronegativities. If the electronegativities of the atoms are similar, the bond is nonpolar. If there is a significant electronegativity difference between the atoms, the bond is polar.
BF3 has a nonpolar covalent bond because the electronegativity difference between boron and fluorine is not significant enough to create a polar covalent bond. In a nonpolar covalent bond, electrons are shared equally between the atoms involved.
In a polar covalent bond, electrons are shared unequally between atoms, resulting in a partial positive and partial negative charge on the atoms involved. In a nonpolar covalent bond, electrons are shared equally between atoms, resulting in no significant charge difference.
