For the formula C6H₁4, calculate the index of hydrogen deficiency (IHD) and select all the types of unsaturation that might be present in the molecule based on the IHD. The IHD is Which types of unsaturation might be present? three double bonds or three ring closings; or two double bonds and one ring closing; or one double bond and two ring closings; or one triple bond and one double bond; or one triple bond and one ring closing no unsaturation; no multiple bonds or ring closings one double bond or one ring closing O many possibilities; most likely a benzene ring

In which of the following cyclic structures are the bonds in the ring 1.5 X the length of a carbon-carbon single bond?     Cylcohexene     Cyclopentane     Benzene     Cyclooctyne     Cyclodec-1,4-diene

How many degrees of unsaturation are present in a molecule with a molecular formula of C9H16.

C6H12 From the chair conformation, rotate about the carbon-carbon bonds of the ring to form a boat conformation. In the boat conformation carbon atoms 1 and 4 are both above (they could also both be below) the plane described by carbon atoms 2, 3, 5 and 6. Look through each of the C-C bonds in the cyclohexane ring. Do you observe any eclipsing interactions? If so, describe what atoms/substituents are eclipsing.
