Question

describe the symmetries of each molecule shown.
a. benzene b. water c. hydrogen peroxide
a. describe the symmetries of the benzene molecule. select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice.
o a. the benzene molecule has line(s) of symmetry, point symmetry, and the following rotational symmetry(ies) °
(use a comma to separate answers as needed. do not include the degree symbol in your answer.)
o b. the benzene molecule has line(s) of symmetry and does not have rotational symmetry
o c. the benzene molecule has the following rotational symmetry(ies) °, point symmetry, and does not have reflectional symmetry
(use a comma to separate answers as needed. do not include the degree symbol in your answer.)
o d. the benzene molecule does not have any symmetry.

Explanation:

Step1: Analyze benzene's symmetries

Benzene is a regular - hexagon - shaped molecule. It has 6 lines of symmetry.

Step2: Check point symmetry

A benzene molecule has point symmetry as it looks the same when rotated 180° about its center.

Step3: Determine rotational symmetry

Benzene has rotational symmetries of 60, 120, 180, 240, 300, 360 degrees.

Answer:

A. The benzene molecule has 6 line(s) of symmetry, point symmetry, and the following rotational symmetry(ies) 60,120,180,240,300,360
