In a polar covalent bond electron are shared?
Yes, in a polar covalent bond, electrons are shared between atoms. However, unlike in a nonpolar covalent bond where the electrons are shared equally, in a polar covalent bond, the electrons are shared unequally. This results in a partial positive charge on one atom and a partial negative charge on the other atom, creating a dipole moment within the molecule.
Yes, in a polar covalent bond, electrons are shared between two atoms. However, the sharing is not equal, resulting in an imbalance of electron distribution and creating partial positive and negative charges on the atoms involved in the bond. This happens when two atoms with different electronegativities (ability to attract electrons) are bonded together. The more electronegative atom will attract the shared electrons closer to itself, creating a slightly negative charge, while the other atom will have a slightly positive charge.
In a polar covalent bond, electrons are indeed shared between atoms. However, the sharing is not equal. Unlike in a nonpolar covalent bond where electrons are shared equally, in a polar covalent bond, the electrons are shared unequally, leading to a partial positive charge on one atom and a partial negative charge on the other.
To determine if a bond is polar or nonpolar, you need to consider the electronegativity difference between the two atoms involved. Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. The greater the electronegativity difference, the more polar the bond.
To find the electronegativity values, you can refer to the periodic table or use a reliable source. Once you have the electronegativity values of the atoms in question, calculate the difference between them. If the electronegativity difference is between 0.5 and 1.7, the bond is considered polar covalent. If the difference is less than 0.5, the bond is nonpolar covalent.
Remember that polarity is based on the overall molecule, not just individual bonds. So, if a molecule has polar bonds but is arranged symmetrically, it can still be nonpolar overall.
It is important to note that polar covalent bonds are intermediate in nature between ionic and nonpolar covalent bonds.
