(a) which of these structures has the most angle strain? staggered butane 1,1-dimethylcyclobutane

1,1-dimethylcyclobutane

Explanation:

The 90 ° angles between carbon atoms are significantly strained and as such have higher binding energies than any linear butane molecules or larger homocyclic alkanes such as cyclohexane.

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.
