More on chem bond..

Today got back my atomic structure test..Gah! well,i can say that i failed again..this was due to carelessness and lack of understanding for I.E *sigh* WHY MUST I ALWAYS FAIL CHEM!! OF ALL MY H2 SUBJECTS! grrr...i am kinda unhappy about this..SO UNHAPPY..i guess i really have to work harder in order to catch up and well hopefully do well for promos..

Well, learned new stuff in chem bonding.Van der waals attractions,Permanent dipole-dipole attractions and hydrogen bond.

For Van der waals forces,it is an induced dipole0dipole attraction,non-polar molecules and molecules are induced at different time.Therefore,it has different electrons distributions and are very weak.

For permanent dipole-dipole and hydrogen bond still have to read up xD hehe...

And there is like chem hmwk to do!!! TTYL =)
