I'm having problem with a question. It's about hybridiztion and geometry. The question has to do with resonance. It's a carbon chain with 2 ethers and a double bon one carbon away from one ether. The book says the O closest to the double bond is sp2 and is trigonal planar and the other O is sp3 bent. I dont see how the 1st one is trigonal planar. I get through the resonance structure how it would be sp2 but i'm not getting the trigonal planar!
