3 Bonding & Chemical Interactions Flashcards
1
Q
formal charge
A
V - N(nonbonding) - (1/2)N(bonding)
2
Q
London dispersion forces
A
weakest IM force (individually)
attraction/repulsion is short-lived
rapidly shifting dipoles in nonpolar covalent bonds
3
Q
dipole-dipole interactions
A
solid and liquid phases
negligible in gas phase
similar to LD, but longer (stronger) duration
4
Q
hydrogen bonds
A
F, O, N
strong type of dipole-dipole interaction
5
Q
In Lewis acid-base chemistry, one atom provides both bonding electrons
A
coordinate covalent bond
6
Q
relationship: bond energy to bond length
A
> bond energy (harder to break), < bond length (more shared electrons)
