    Alcohol X has the structure (CH3)2 C(OH)CH(CH3)2

    Give the structure of, and name an isomer of 2,3-dimethylbut-2-ene which is also formed in the reaction. Explain why two products are obtained

    You can find this question if you just copy and paste the question on google, but does anyone know how to go about getting the answer?

    Well firstly is that the complete question?

    For instance, is it asking to give the structure of Alcohol X or of 2,3-dimethylbut-2-ene, or of something else?

    And what reaction are we talking about that produces this isomeric compound?

    I'm assuming a dehydration reaction since we're going from an alcohol to an alkene.

    Draw the alcohol out. In a dehydration reaction we're removing the -OH group. But notice that once we do that, the carbon atom with that -OH group will now be only making three bonds. To fix this, we make a double bond with an adjacent carbon atom (and you have three pick from)

    That double bond causes the chosen adjacent carbon atom to now make five bonds. To fix this, a hydrogen atom is removed. (See how the net effect is to remove a water molecule?)

    One of the possible products is given in the question. That's formed if your adjacent carbon atom is no. 3.
    i.e. (CH3)2 C(OH)CH(CH3)2 (in bold)

    If you picked a different adjacent carbon atom, you may potentially get a different compound...
