Hey guys I'm in deep trouble, since Lewis structures come for around 3 marks or so and I don't get them some time, Most of my query concern:
A) Is it a dative(isn't someone supposed to tell me this?), are all the electrons coming from this atom? [OH-] Is a doubt for this reason!
B) How do I form the bonds to satisfy the octet rule
C) How on earth do I know when its an extended octet??

Thanks!

You really should ask your teacher for some time to work together and ask him these questions directly.
