OChem: MgCl with D20

so this is the rxn.

MgCl is attached to cyclohexane (don't know how to name this correct 😀😀)

if this molecule were reacted with D20(isotopes of Hydrogen),

why is the product D-(attached to)cycloheane instead of DO-cyclohexane?

thanks!! guys!!

The carbon directly attached to MgCl has a high partial negative charge. The partially negative carbon will attack the positive D from the D2O to create cyclohexane with a D where MgCl used to be.

This partially negative carbon cannot attack Oxygen because Oxygen bears a partial negative charge as well; in D2O or H2O, H bears a partially positive charge while O bears a partially negative charge.

Hope that helps.
