Question

Three charged particles are at the corners of an equilateral triangle.

A) Forming a linear chain
B) Creating an isosceles triangle
C) Resulting in an acute triangle
D) Arranged in an equilateral triangle

Answer 1

A molecule with three electron groups adopts the positions of an equilateral triangle, 120° apart and in a plane, forming a trigonal planar shape. An example is BF3.

Step-by-step explanation:

A trigonal planar shape refers to a molecular geometry that occurs when three atoms or groups of atoms are arranged in a plane with bond angles of 120 degrees. This arrangement is commonly observed in molecules with a central atom bonded to three surrounding atoms or groups. The term "trigonal" refers to the three equivalent positions, and "planar" indicates that these positions lie in a flat or two-dimensional plane.

A molecule with three electron groups orients the three groups as far apart as possible. They adopt the positions of an equilateral triangle, 120° apart and in a plane. The shape of such molecules is trigonal planar. An example is BF3.
