sn1

Question 1

what happens in sn1

Answer 1

racemic mix is made due to the trigonal planar shape of the CC+ (sp2 hybridised) R+ S formed
nucs can attack the empty p orbitals from any side.

Question 2

what else can happen instead of racemization

Answer 2

inversion of configuration
bc halide is still close to CC+ and repels the nuc

nuc attacks the opposite side of the bond broken

Question 3

why do benzenes or double bonds normally undergo sn1 even if they’re primary alpha carbons

Answer 3

they can stabilise the CC+ using mesomeric effects

(eg: positive charge is shared between more C’s)
