Question

please explain why/how the electrons flow in this reaction

her HO: me + C I-O-I : H-c-I: HO-C-H. 210

Answer 1

As OH- is a good source of electron i.e neucliophile hence it's gives electron to the electrophilic carbon center by knocking out l- which is a very good leaving group .

The reaction proceed via Sn2 mechanism as carbon is 1 degree.so I^-_{can't leave the system before the attack of OH- .}
