In a heteronuclear molecule a bond is build between different atoms, and the most important difference from the homonuclear case is that molecular orbitals (MOs) are no longer shared exactly between atoms. As like a molecule where each atom has just one valence atomic orbital (AO): As like would be gas-phase LiH with 2s on Li and 1s on H. When MOs are build using the LCAO approximation.
the coefficients c2 and c1 are no longer equal. In LiH the two AOs differ greatly in energy, as H has a bigger ionization energy and higher electronegativity than Li. If is the AO of lower energy (i.e. of higher ionization energy or greater electronegativity;), then the bonding MO has c2>c1.
From the point of view of "green chemistry" - why should reactions be carried out in CO 2 instead of using carbon monoxide or phosgene (2 reasons)? Apart from the compression of c
between nitrobenzene and phenol which is more reactive towards chlorine and why? Upon reaction with chlorine what products can be formed from the two reactions.
Atoms consists of protons, neutrons and electrons. If the mass of neutrons and electrons were made half and two times respectively to their actual masses, then the atomic mass of
Where is tin obtained? Ans) Tin is obtained in several places tin is found mainly in the ore cassiterite, which is originate in Malaysia, Bolivia, Thailand, and Nigeria.
