Chapter 3 - Hybridization Flashcards
(4 cards)
1
Q
How many bonds can carbon, nitrogen, and oxygen make with FC of zero
A
Carbon 4 bonds
Nitrogen 3 bonds and 1 lone
Oxygen 2 bonds and 2 lone
So you count how many valence electrons and that’s how many bonds and then whatever is left to get to 4 is how many lone pairs
2
Q
How do you make a neutral molecule have a positive formal charge?
A
Take a lone pair and make it a bonding pair
3
Q
Valence Bond Theory:
A
Electrons localized between atoms and bond formed by sharing of electrons
“localized electron theory”
4
Q
Define sigma and pi bond
A
Sigma is head on overlap of hybridized orbitals
Pi is side on overlap from unhybridized p orbitals
