 Okay, so help me draw this molecule up here. What's the structure of cyclohexylmethyl ether? So what do we have to do first? Okay, you want to draw a cyclohexane and then what? Attach that to an oxygen. And the oxygen, right, is attached to a methyl. And that's it. So that's how you draw simple ethers. Again, right, cyclohexylmethyl ether is saying that attached to the ether oxygen is a cyclohexane ring and a methyl group. Okay, any questions on this one?
