Consider the molecule of furan. Its Lewis structure is shown. H X Is furan polar? If yes, consider which side of the molecule has partial negative charge and which - partial positive. Then, indicate the direction of the dipole moment relative to the molecule as shown. Non-polar, zero dipole moment. Polar, the dipole vector points along one of the C-O bonds. Polar, the dipole vector points along one of the C-H bonds. Polar, the dipole vector points along the vertical axis. Polar, the dipole vector points along the horizontal axis.
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
Is furan polar? If yes, consider which side of the molecule has a partial negative charge and which has a partial positive charge. Then, indicate the direction of the dipole moment relative to the molecule as shown.

**Explanation of the Diagram:**
The diagram illustrates the Lewis structure of furan, which consists of a five-membered ring with four carbon atoms and one oxygen atom. The structure features alternating double and single bonds, with each carbon atom bonded to a hydrogen atom, and lone pairs on the oxygen atom.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faab01dc0-572f-4647-affc-231aefa5eea9%2Ffe9602e0-14f4-4b0b-aaa4-71a95d9bf57f%2F0tfvjg6_processed.jpeg&w=3840&q=75)
