Illustrate the orbital overlap between the bonding electrons in
water.
Which two orbitals overlap when a chlorine atom and an iodine
atom overlap to form a covalent bond? Draw an illustration of the
orbital overlap. Are the bonding electrons shared equally between
the two atoms? Explain your reasoning.
Which hybrid orbitals overlap in the C - O bond in
CF₂O? Which hybrid orbitals overlap in the C - O bond in
CF₂O?
A) sp² - s
B) sp² - sp²
C) sp² - sp³
D) sp³ - sp³
E) sp³ - sp
From the output calculations the Homo value is (-7.513) and LUMO is
(-3.335) so the calculated band gap was 4.17 ev .
According to the following equation :
Wavelength(in nm)=1240.8/Energy(in eV) = 297.55 nm
My question is why I got this small wavelength 297.55 mm while
the maximum wavelength from UV-VIS was above 500 mm ??
