Unit 1: Intermolecular forces Flashcards
What are the three intermolecular forces?
hydrogen bond
vander waal
ionic
Vander Waals bonding strength
weakest
Vander Waals bonding is what type
Partial and induced
What is Partial
sharing but hogging, whole charge not given away
what is formal
whole electron taken/given
what is induced
temperary
what is permanent
always going to share
Polar bonding is when
sharing electron but one element wants it more
non polar bonding
elements share electron equally
Weak vs really weak
weak- still holds shape
really weak, won’t hold shape
Hydrogen bonding
is partial and permanent
Ionic bonding is
permanent and formal
it takes energy to ___ bonds
break
Energy is released when you ____ Bonds
form
Why/how do ionic bonds form
to fill valence shell
Ions, take/give electron to fill valence shell then when in water the water molecules separate and weaken the bond
why/how does Vander waals bonds form
stronger together
push very close together electron movement in atoms start to sync
why/how do hydrogen bonds form
the neg. charge pulls in that partial charge atoms
the neg. partial charges will attract the pos. partial charges,
Non polar covalent bonds form in which bond
Vander Waals
Polar covalent bonds form in which bonds
hydrogen
Melting does what to bonds
breaks weak bonds
Freezing does what to bonds
forms weak bonds
Ionic bonds are associated with what
ions
Hydrogen bonds are associated with what molecule
polar
Van der Waal bonds are associated with what molecule
Non-polar
