D. Linear
E. Trigonal planar

NBr3 - Trigonal pyramidal

SO2- Bent

SBr42+- Tetrahedral

SO42- Tetrahedral

CF3Cl - Tetrahedral

Explanation:

The shape of a molecule depends on the number of electron pairs on the valence shell of the central atom in the molecule. This is well captured in the valence shell electron poair repulsion theory.

The number of electron pairs on the outermost shell of the central atom in a molecule are called regions of electron density. According to this theory, these regions of electron density must be positioned as far apart from each other as possible to minimize repulsions between electron pairs.

This theory is the basis of the shapes of molecules shown in the answer. If a molecule has four regions of electron density, it could be trigonal pyramidal or tetrahedral in shape such as NBr3 and CF3Cl.

Note that, when deciding on the three dimensional geometry of a molecule, only the covalent bonds present are considered.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

i just learnt this recently but i need to look through my notes again
