Haloalkanes, more polar/less polar for reaction
All I remember learning is that SN2 prefers polar aprotic, and SN1 prefers polar protic. What's the concept behind this question?
(both statements are true)

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.A polar protic medium will protonate your functional group and try to form carbocation. If a carbocation can't form, protonation still reduces the electron density on the functional group itself. Not ideal for SN2.
In general, polar solvents try to ionise the solutes. If you don't want ions, you take something which isn't as polar. You can think of it as the dipole moment causing an electron shift in the reagent molecule, inducing a dipole moment of its own, which can tear it apart.
yeah first part makes sense
for the second part
so the ammonolysis reaction proceeds well in the more polar medium because uhh
it makes a lot of ions?
1st one makes some sense because the transition state may be disturbed by too much polar activity i guess
It makes a salt. Very ionic by nature.
fair enough
is this correct?
Yeah basically
bet thanks
