Question

Question 9 The cyan curved line in the diagram to the right represents an electron-pushing arrow. Indicate whether the arrowhead should be a single-barbed arrow or a double-barbed arrow and whether the direction of the arrow should be clockwise or counter-clockwise. Both answers are needed for this question to be completely correct The lone pairs on the heteroatoms have been deliberately removed from the structures below to avoid giving away the answer. But remember electron flow arrows MUST always originate from a source of electron density (lone pair or bond) your knowledge of organic chemistry to determine which atoms would have lone pairs and then answer the question. CH ?? Single-barbed Arrow Double-barbed Arrow Clockwise Counter-clockwise None of the above

Answer 1

The arrows are Double-barbed arrow and the direction is Counter-clockwise

Explanation: The electron density on oxygen atom abstracts proton and produces iodide ion so the arrow started on oxygen atom and moved in counter-clockwise direction.
