7. Hybridisation for a molecule is given by: 1 2(V + H − C + A) 1 2 ( V + H − C + A) Where, V = Number of valance electrons in central atom. H = Number of surrounding monovalent atoms. C = Cationic charge. A = Anionic charge. If this expression is 2 then its sp s p hybridised, 3 then sp2 s p 2 hybridised and so on.Thanks for contributing an answer to Chemistry Stack Exchange!

CH3 radical is Sp2 hybridised carrying the lone electron in a pure p orbital. This is so because Sp2 hybridised orbitals are lower in energy than Sp3 hybrid orbitals (The more the S character the lesser is the energy of the orbital). When there is a lone electron present, it is more efficient to keep the bond pair electrons in lesser ...

Today I stumbled across a website which defined the titration of weak acid and strong base as the following: "The titration of a weak acid with a strong base involves the direct transfer of protons from the weak acid to the hydoxide ion. The reaction of the weak acid, acetic acid, with a strong base, NaOH, can be seen below.

May 28, 2015 · Today this reversible lithium-halogen exchange reaction can be formulated as, RLi +R′X↽−−⇀K R′Li +RX. R L i + R ′ X ↽ − − ⇀ K R ′ L i + R X. As an equilibrium process, we know that the more stable lithium species is preferred. Interestingly when R′ R ′ = aryl (particularly bromides and iodides) this is best written as, Data Exchange.
