Question

line, wedge and dash drawings
when drawing lewis structures, we can include information about the 3d structure by using a combination of lines, wedges, and dashes:
line: bond is in the same plane as the paper:
wedge: bond is coming forward, in front of the plane of the paper:
dash: bond is going backward, behind the plane of the paper:

1. where are each of the 5 atoms in the molecule chfclbr?

in the plane of the paper:
in front of the plane of the paper:
behind the plane of the paper:

Explanation:

Step1: Identify atoms with line bonds

Line represents atoms in - plane. Here, \(H\), \(C\), \(Br\) have line - like bonds (assuming the main - chain representation for \(C\) as central atom with \(H\) and \(Br\) in - plane as per typical Lewis structure drawing conventions for such tetrahedral - like arrangements where \(C\) is central).

Step2: Identify atoms with wedge bonds

Wedge represents atoms in front. \(F\) has a wedge bond.

Step3: Identify atoms with dash bonds

Dash represents atoms behind. \(Cl\) has a dash bond.

Answer:

In the plane of the paper: \(H\), \(C\), \(Br\)
In front of the plane of the paper: \(F\)
Behind the plane of the paper: \(Cl\)
