    How do you name this compound??

    I'm thinking its a bispiro with a cyclopropyl and an ethyl substituent

    Yours truly,

    PS: Its only one compound, the picture on the left is just a rotation of the one on the right.

    It looks like a decalin compound, also known as a bicyclo[4.4.0]decane. That should get you started.
    Now you need to figure out the numbering system for this decahydronaphthalene compound.

    shouldn't it be a spiro compound?

    i'm not sure but we just took this in class this week and we've been taught that if the carbon atoms are shared its supposed to be called a spiro compound.

    spiro compounds have only 1 carbon common to both rings. This has two.
