Chapter 1: Carbon and its compounds Flashcards
What is a nodal plane?
It is the area where the value of orbital is exactly 0, hence it is also a place where the probability of finding an electron is exactly 0.
What fixes the energy of orbitals?
The specific electron distribution properties.
What are degenerate atomic orbitals?
Set of orbitals with the same energy value such as 2P orbitals.
2px, 2py and 2pz have the same energy.
How much energy do you need to have for something in chemistry to be sta
Which orbital is the most stable?
The lowest energy orbital, ususally 1s
Think about the interactions…
How do atoms behave in a molecule that they form themselves?
The behaviour of atoms in a moclule is dominated by their inteactions with neighbouring atoms. These interactions hold the organic molecule together and also impart to the molecule’s chemical and physical character.
Think about forces or attractions
What holds the bonds together?
Attractions between atoms hold the atoms together. The force of attraction is called electrostatic attraction.
think about where the electrons are in a cv bond..
In a covalent bond where is the highest probability of finding electrons
In between both the nucleus.
What controls the type of bond being formed in terms of sigma or pi?
The type of atomic orbitals involved in bonding.
How do Molecular orbitals form?
From different linear combinations from of the Atomic Orbitals.
Ie what does antibonding or Inphase depend on?
On what does the type of bond form depend on?
Molecular orbits depend on relative phases of overlapping lobes of the inteacting atomic orbitals.
How is the energy in the anti bonding?
It is high in energy, and is cylindrically symmetric about the bond axis.
Why does p bond have lower energy than sigma bonds?
Because the pi bond’s orbitals are not directly pointing each other so they are not as strong.
True/ False: The probability of finding electrons along the x-axis is high in pi bonds.
Flase, as they do not overlap on the axis but they have a side-side overlap.
