Resonance effect or mesomeric effect (1) The effect where electrons are transferred from a multiple bond to a molecule, or from a multiple bond to a one covalent bond or lone p
Which of the following represents the electronic configuration of an element with atomic number 17: (1) 1s 2, 2s 2 , 2p 6 , 3s 1, 3p 6 (2) 1s 2 , 2s 2 , 2p
5H is the most stable, and the least stable isotope is 7H
how it works, give me some examples
The wavelength of the radiation emitted, when in a hydrogen atom electron falls from infinity to stationary state 1, would be (Rydberg constant 1.097 x 10 7 m -1 ) (1) 406 nm
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
Problem: Let us calculate Q value of the reaction 27 Al (d, α) 25 Mg Answer: Given that masses of 27 Al = 26.981541 2 H = 2.014102 4 He = 4.
