Draw two additional resonance structures for the following compound. Q. In the spaces provided, draw all the important resonance contributing structures of the indicated species.
What is important as well, is that not all the resonance structures are equally stable. In fact, the most stable resonance form is the resonance hybrid since it delocalizes the electron density over a greater number of atoms:This structure is more stable than the others because the electrons on the methyl group can directly stabilize the electron deficient carbocationic carbon. This stability is passed on to the resonance hybrid, which makes the intermediates for attack at the more stable than that for attack at the meta position.
Resonance Structure is one of two or more Lewis structures for a single molecule that can not be described fully with only one Lewis structure.

In case of (II), the − I effect of the oxygen atom is higher since it is near the carbocation when compared to (I). Since higher the − I effect, higher the instability of the carbocation, (I) is the most stable resonating structure among the given canonical structures due to alternate loan pair, and double bond which stabilizes the carbocation by resonance. The lone pair on nitrogen in these resonance structures (even though they are not the most important ones) is enough to bend the molecule.

Determining formal charge yields the following: The structure with a terminal oxygen atom best satisfies the criteria for the most stable distribution of formal charge: The number of atoms with formal charges are minimized (Guideline 2), and there is no formal charge larger than one (Guideline 2).
Resonance structures are sets of Lewis structures that describe the delocalization of electrons in a polyatomic ion or a molecule. In many cases, a single Lewis structure fails to explain the bonding in a molecule/polyatomic ion due to the presence of partial charges and fractional bonds in it. The most stable structures contribute most to the resonance hybrid. They are called the major resonance contributors. In order of importance, a major contributor must have: The most atoms with complete octets. Any formal charges on the atoms most able to accommodate them. The most covalent bonds. The smallest number of formal charges.
In general, a resonance structure with a lower number of total bonds is relatively less important. 8) The resonance contributor in which a negative formal charge is located on a more electronegative atom, usually oxygen or nitrogen, is more stable than one in which the negative charge is located on a less electronegative atom such as carbon. Jun 01, 2019 · Stochastic resonance (SR) is used widely as a weak signal detection method by using noise in many fields. In order to improve the weak signal processing capability of SR, a novel composite multi-stable model is proposed, which is constructed by the joint of the tristable model and the Gaussian Potential (GP) model.

If you have many possible resonance forms, you choose the most likely resonance form by calculating the formal charge on each atom in each resonance form. In these situations it is helpful to calculate the formal charge on each atom in each possible resonance structure, and use the formal charges to determine the most representative structure.
Sometimes, resonance structures involve the placement of positive and negative charges on specific atoms. Because atoms with electric charges are not as stable as atoms without electric charges, these resonance structures will contribute less to the overall resonance structure than a structure with no charges.

Most structures and machines are capable of exhibiting natural oscillations so that a periodic external force may induce resonance. For example, a bridge may resonate as a result of the action of periodic impulses caused by a train passing over rail joints, or the foundation of a structure or a machine itself may resonate because of imperfectly ... Three canonical resonance contributors may be drawn, and are displayed in the following diagram. The two structures on the left have one discrete benzene ring each, but may also be viewed as 10-pi-electron annulenes having a bridging single bond. The structure on the right has two benzene rings which share a common double bond.
The resistance offered by a structure to undesirable movement like sliding, collapsing and over turning etc is called stability. STABLE STRUCTURES: A stricter is said to be stable if it can resist the applied load without moving OR A structure is said to be stable if it has sufficient number of reactions to resist the load without moving.
