Which of the following is TRUE? 1. Resonance structures are real molecules that are in equilibrium with each other in solution. II. Resonance structures are drawings that differ in the position of electrons, not in the position of atoms. III. The energy of the actual species is higher that the estimated energy of any of the species resonance structures. IV. Resonance structures are always equivalent. Select one: O A. IV OB. II O C. I D. III
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.
Resonance structure: If the Lewis structure of a molecule or ion cannot explain by a single structure then more than one Lewis structure is written, these Lewis structures are different by the position of the lone pair of electrons and the pi bond. These structures are called resonance structures.
