Current Question (ID: 21320)

Question:

$\text{Identify the staggered conformation with maximum dihedral angle:}$

Options:

1. $\text{H}$ $\text{H}$ $\text{CH}_3$ $\text{CH}_3$
2. $\text{CH}_3$ $\text{H}$ $\text{H}$ $\text{CH}_3$
3. $\text{H}$ $\text{H}$ $\text{CH}_3$ $\text{CH}_3$
4. $\text{H}_3\text{C}$ $\text{H}$ $\text{CH}_3$ $\text{H}$

Solution:

$\text{A dihedral angle is the angle that separates a bond on one atom from a bond on an adjacent atom.}$ $\text{The staggered conformation with the maximum dihedral angle is the anti-confirmation, where two larger groups are } 180^\circ \text{ apart.}$ $\text{In the staggered form, the groups attached to adjacent carbon atoms are positioned as far apart as possible to minimize torsional strain.}$ $\text{The staggered conformation with maximum dihedral angle:}$ $\text{CH}_3 \text{H} \text{H} \text{CH}_3$ $\text{Hence, option 2 is the correct answer.}$
