Transition metals, like copper, are found in many types of biological molecules where it is common for metals to have deviations from ideal bond angles. Plastocyanin, a protein involved in electron transfer, contains a copper atom bonded to nitrogen or sulfur atoms found in amino acids. The bond angles range between 100° and 108°. What type of geometry best describes the sulfur center affected by the copper atom in plastocyanin?

Tetrahedral is the correct answer to this question.

Explanation:

Tetrahedral:-

The term used to classify molecules and polyatomic ions which have one atomic in the middle and four electrons in the edges of the tetrahedron. Tetrahedral is a molecular shape that occurs when there are four bonds and thus no single pairs across the main atomic in the sample. The atoms bound to the nitrogen carbon lie at the edges of the tetrahedron with 109.5 ° bends among themselves.

Examples of tetrahedral:-

The bond angle for both methane and ammonium is 109.4.
