Due in two hours, I can't figure it out! I spent 45 mins on this

Homework Statement

Give the isomers of C₄H₁₀O that are ethers

I am doing this on Mastering Chem and it isn't working

I don't understand, I've got a cis and tran, what's going on?

Why do you care about CIS and TRANS? You are looking for isomers of ethers using C₄H₁₀O, and you only entered one single drawn model. You should easily be able to find other arrangements for those numbers of atoms. You should only need models using single-bonds. Think: shorter or longer chains of carbons; other positions for the oxygen; any branches other than just methyl groups?

 

[Borek]

These are not not cis and trans, what you have is the same molecule repeated twice.

hi flyingpig!

pardon a non-chemist for asking …

but why are you drawing them diagonally when it seems easier to do it horizontally?
