Consider the molecules of furan and benzene. The dominant Lewis structure of furan and the two resonance structures of benzene are shown below: Furan H H K H Benzene XX-X Compare the C-C bonds in benzene to the C-C bonds in furan. Based on the given structures, which one of the following dual statements is correct? In furan, the C-C bonds have different lengths: one is longer than the other two. In benzene, all six C-C bonds have equal lengths. In furan, all three C-C bonds have equal lengths. In benzene, the C-C bonds have different lengths: three are longer than the other three. In furan, the C-C bonds have different lengths: one is shorter than the other two. In benzene, all six C-C bonds have equal lengths. In furan, the C-C bonds have different lengths: one is longer than the other two. In benzene, the C-C bonds have different lengths: three are longer than the other three. In furan, all three C-C bonds have equal lengths. In benzene, all six C-C bonds also have equal lengths.
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
