chapter 6 shapes of molecules and IMF Flashcards
1
Q
why do lone pairs repel more than bonding pairs?
A
slightly closer to central atom so occupy more space than bps
2
Q
what do different wedges mean when drawing 3D shapes of molecules?
A
solid line is a bond in the plane of the paper. solid wedge comes out of the plane of the paper towards you. dotted wedge goes into the plane of the paper away from you
3
Q
what is the order of increasing repulsion between different electron pairs?
A
bonded-pair/bonded-pair < bonded-pair/lone-pair < lone-pair/lone-pair
