Question

question
consider the following newman projection:

what word or two-word phrase describes this conformation?
how many br atoms are gauche to the h atom on the back carbon?
how many br atoms are anti to the h atom on the back carbon?
how many br atoms are eclipsing the h atom on the back carbon?
your answer

Explanation:

1. This Newman projection shows atoms on the front carbon staggered (not overlapping) with those on the back carbon, fitting the staggered conformation definition.
2. Gauche means a 60° dihedral angle; there is 1 Br atom at this angle to the back H.
3. Anti means a 180° dihedral angle; no Br atoms are positioned this way relative to the back H.
4. Eclipsing means a 0° dihedral angle (overlapping); no Br atoms overlap with the back H.

Answer:

What word or two-word phrase describes this conformation? Staggered conformation
How many Br atoms are gauche to the H atom on the back carbon? 1
How many Br atoms are anti to the H atom on the back carbon? 0
How many Br atoms are eclipsing the H atom on the back carbon? 0
