What is happening in this diagram? 4 iterations of the following structure: 2 carbons double bonded to each other, each bonded to H above, the left C bonded to H below and the right to R below. The chain begins with an I and a dot. A curved arrow points from the dot to the space before the first structure above; curved arrows point left and right from the double bonds to the spaces before and after the structures. Arrow points to a long chain of carbons, I at the beginning of the chain. The carbons are all bonded to H above, and alternate bonding to H and R below. Polymers are forming large monomers. Monomers are forming large polymers. Polymers are breaking down into monomers. Monomers are breaking down into polymers.

The correct answer is c

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
