What is the angle between electron groups in the trigonal planar electron geometry?

1 Answer

Jun 13, 2016

If I can circumscribe an equilateral triangle inside a circle, what do you think it should be?

Explanation:

For $M X_{3}$ $MX_3$ , in which $M$ $M$ has trigonal planar coordination, $∠ X - M - X$ $/_X-M-X$ $=$ $=$ $120^{\circ}$ $120^@$ .

Examples of real molecules that assume this geometry are $B C l_{3}$ $BCl_3$ , and $A l C l_{3}$ $AlCl_3$ .
