(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.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
