Question

Methane (CH 4 ) and the perchlorate ion (ClO 4− ) are both described as tetrahedral. What does this indicate about their bond angles?

A) 90 degrees
B) 109.5 degrees
C) 120 degrees
D) 180 degrees

Answer 1

Methane (CH4) and the perchlorate ion (ClO4−) have a bond angle of approximately 109.5 degrees due to their tetrahedral geometry.

Step-by-step explanation:

Both methane (CH4) and the perchlorate ion (ClO4−) are described as having a tetrahedral geometry. This indicates that their bond angles are approximately 109.5 degrees. This arrangement brings the corners of a tetrahedron further apart compared to a planar arrangement, resulting in bond angles larger than 90 degrees.
