I need your help

I need your help to answer the 2 question in the attachment. I really have hard time in organic.

The first one is just asking for resonance structures. A resonance structure being a different "version" of the molecule, where everything is connected the same, just the electrons are different. I attached an example.

 

Hybridization is determined by how many regions of electron density are around an atom. In CO2 (carbon double bonded to an oxygen on each side), there are 2 regions of electron density (each double bond counts as one). This indicates that 2 orbitals need to hybridize at this atom. Thus the hybridization is sp (one s, and one p orbital). In CH4, there are four regions of electron density, so the hybridization is sp3 (1 s, 3 p's).
