MARK SCHEME – AS CHEMISTRY – 7404/2 – JUNE 2021 9 3 3.14 Organic reaction mechanisms Curly arrows should originate either from a lone pair of electrons or from a bond. The following representations should not gain credit and will be penalised each time within a clip. H3C Br _ : H C . Br H3C . .Br .. _ OH OH For example, the following would score zero marks. H H3C C Br HO H When the curly arrow is showing the formation of a bond to an atom, the arrow can go directly to the...

subsequent equation or observation) can be scored from an incorrect attempt (possibly an incomplete reagent) at the correct reagent. Specific details will be given in mark schemes. For example, no credit would be given for  the cyanide ion or CN– when the reagent should be potassium cyanide or KCN;  the hydroxide ion or OH– when the reagent should be sodium hydroxide or NaOH; MARK SCHEME – A-LEVEL CHEMISTRY – 7405/2 – JUNE 2021 6  the Ag(NH3)2+ ion when the reagent shoul...
