is it possible to have a cis-1-tert-butyl-2-methylcyclohexane that is equitorial for both substitutents? I would think that the tert group would need to be equitorial, while the methyl would be axial, since cis cannot have two equitorials directly next to one another, but am I wrong? I'm confused.

- I don't understand why the first one and second one are cis and trans respectively. Wouldn't the first one be trans-1,2-dimethylcyclobutane because the torsional strain wouldn't allow the carbons to be in the same conformation. Meaning one of the carbons would be up and then the next would be down and so on. Since both methyl groups are equatorial and the first and second carbons are arranged up and down, wouldn't it be trans. Same logic for the second molecule. Carbon 1, which is attached to the methyl is down, carbon 3 which is attached to the methyl should be down also because of torsional strain, and since both methyl are in axial (or equatorial?), it would be cis. Or is it based off of the way the carbons are positioned in the picture?Draw a resonance structure, complete with all formal charges and lone (unshared) electron pairs, that shows the resonance interaction of the cyano with the ortho position in benzonitrile.
