25.11 Types of Bonds Flashcards
1
Q
covalent bond
A
bond formed when 2 atoms each share 1 unpaired valence electron
2
Q
polar
A
uneven electron density in a molecule (has dipole moment)
3
Q
coordinate covalent bond
A
bond formed when 1 atom donates 1 electron pair (same atom donates both electrons)
4
Q
Lewis base
A
thing that donates electron pair (nucleophile/ligand)
5
Q
Lewis acid
A
thing that accepts electron pair (electrophile)
6
Q
ionic bond
A
bond formed by gaining or losing an electron with another species
7
Q
in an ionic bond, what is the bond strength proportional to?
A
1) more charge on ions => stronger
2) more distance distance => weaker
3) larger radii => weaker
8
Q
what is needed for an ionic bond to form?
A
needs to be a large difference in electronegativity between the two participants
