Draw the major organic substitution product(s) for (2r,3s)‑2‑bromo‑3‑methylpentane reacting with the given nucleophile. clearly drawn the stereochemistry, including a wedged bond, a dashed bond and two in‑plane bonds at each stereogenic center. omit any byproducts.

Look at the picture. Due to you not mentioning the nucleophile i will be general.

Explanation:

In this case if we perform reaction this reaction it will undergo SN2 mechanism. Better to take polar nonprotic solvent like DMF or DMSO. And due to our mechanism the inversion of stereocenter will occur.

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.
