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

#1 is a pretty classic resonance stabilization problem.  Review rules for valid resonance structures in your text or here: (http://www.cem.msu.edu/~reusch/VirtTxtJml/intro3.htm#strc7, or http://homepage.smc.edu/kline_peggy/Organic/Rules_for_Resonance.html) and suggest an answer.  We'll tell you if you're right or not.

#2 is knowing how multiple bond correspond to hybridization of carbon.  Review hybrid orbitals and multiple bonds in your text or here: (http://www.cem.msu.edu/~reusch/VirtTxtJml/intro3.htm#strc8) and give it a try first.
