Question

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

Answer 1

Answer:

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.

Answer 2

The structure with the most angle strain is ; ( B ) 1,1-dimethylcyclobutane

The 1,1-dimethylcyclobutane has the most angle strain because of the presence of 90° angle ( which shows strains ) found in-between the carbon atoms in 1,1-dimethylcyclobutane. while staggered Butane has its carbon ( blue ) rotated 60°.

The carbon atoms also have a higher binding energy than staggered ( linear ) Butane molecules.

Hence we can conclude that the structure with the most angle strain is 1,1-dimethylcyclobutane.
