AlCl3preferred to attack the position with larger electron cloud density relatively like C(sp2) position, which was attributed to that AlCl3was a strong Lewis acid, and in HCC-240fa, AlCl4−preferred to attack the position with smaller electron cloud density relatively like C(sp3) position, ...
(sp2) position, which was attributed to that AlCl3was a strongLewis acid, and in HCC-240fa, AlCl4−preferred to attack the position with smaller electron cloud density relatively like C(sp3) position, which was attributed to that AlCl4−was a Lewis base. Our experimental results showed ...
Atomic sp, sp2, and sp3 hybrid orbitals were introduced by Linus Pauling to explain the nature of the chemical bond. Quantum dynamics simulations show that they can be sculpted by means of a selective series of coherent laser pulses, starting from the 1s orbital of the hydrogen atom. Laser ...
