Question

Match each two-dimensional structure to its correct three-dimensional description

The three-dimensional shape of a molecule depends on the number of electron groups around the central atom. Because like charges repel, the molecule adopts a shape that allows the electron groups to be as far apart as possible. Very often, a two-dimensional dot structure does not accurately represent what the molecule would look like in three dimensions. Match each two-dimensional structure to its correct three-dimensional description. Drag the appropriate items to their respective bins.

Answer 1

Linear: When two electron groups attached to a central atom which are oriented as far apart as possible, they are pointed in opposite directions, then the molecule is linear. ㄚㄧㄨㄧㄚ Trigonal planar: When three electron groups around the central atom repel each other to the corners of an equilateral triangle, then the molecule is trigonal planar. ㄚㄧㄨㄧㄚ Bent: When four electron groups around the central atom include two bonding and two nonbonding groups, then the molecule is bent in shape. ㄚㄧㄨㄧㄚ Tetrahedral: All molecules or ions with the four electron groups around a central atom adopt a tetrahedral arrangement. ㄚㄧㄨㄧㄚ Pyramidal: When one of the four electron groups in the tetrahedral arrangement is a lone pair, then the molecule is pyramidal in shape. ㄚㄧㄨㄧㄚ
