Please explain. 0/4 pts Question 5 Electrons exist in orbitals within an atom. Bohr's model described a single electron system well. But the energy level for orbitals change when as you add a second and more electron. In a single electron system, there are (a)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (b) sub-level(s) in the atom. In a multi-electron system, (c)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (d)sub-level(s) in the atom. Bohr was never...
can anyone help me on this? 2. (4 pts) Which is the better nucleophile, chloride or bromide ion and why? Discuss this in the context of the data and in terms of the nature of the chloride ion and the bromide ion. (4 pts) Why is the ratio of bromo to chloro products roughly even when using tert- butanol as the substrate compared to using 1-butanol as the substrate? f(2 pts) Why must the nucleophile mixture be highly acidified for...
