Resonance
Resonance - The phenomenon of resonance was put forward by Heisenberg to explain the properties of certain covalent molecules. Most covalent molecules have a unique Lewis formula (dot structure), which explains the bonding in that molecule. Some molecules lend themselves two or ..

Resonance
A mechanical system which is free to vibrate like a hacksaw blade clamped at one end, a diving spring board or the air in pipes has a natural frequency of vibration f 0 , which depends on its dimensions. When a periodic force of a frequency different from f 0 is applied to the system, it vibrates w..

Effects of Resonance
The effects of resonance is prominent in conjugated systems (having alternate single and double bonds) wherein displacements of electrons from one part of the molecule to another part takes place, creating centers of high and low electron densit..
Large resonance energy
Due to resonance, the p -electron charge in benzene gets distributed over greater area, i.e., gets delocalized. Delocalization results in the energy of the resonance hybrid decreasing relative to the contributing structures, by about 150 kJ mol - 1 . This decrease in energy i..
Resonance or Mesomeric Effect
If two or more structures can be assigned to a molecule, none of which is capable of describing all the known properties of the compound, then the actual structure is known to be a resonance hybrid or an intermediate of these structures. The various structures written are called reso..

The contributing structures should: Have the same atomic positions. Posses the same number of unpaired electrons. Have nearly the same energy. Written in a way that negative charge is present on an electronegative atom and positive charge is present on an electropositive atom. Not pl..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
