Term
not chemical bonding
Definition
hydrogen bonding
Term
extremely important for properties of water and proteins
Definition
hydrogen bonding
Term
what is stronger interatomic or molecular
Definition
interatomic
Term
exception to the octet
Definition
when total # of VE is an odd #
Term
vsepr
Definition
Valence Shell Electron Pair Repulsion
Term
molecular orbitals
Definition
when atomic orbitals overlap
Term
sigma bond
Definition
2 atomic orbitals combine to form a molec. orbital that is symmetrical along the axis connecting the 2 atomic nuclei
Term
what does vsepr say
Definition
states bc electrons repel, molecular shapes adjusts so VE pairs are as far apart as possible
Term
pi bond
Definition
side by side orbitals: pi molecular orbitals filled with 2 electrons found in regions above or below the axis
Term
is pi or sigma stronger
Definition
sigma is stronger
