Write an equation for the proton transfer reaction that occurs when the following acid reacts with water. Draw curved arrows that show a mechanism for the proton transfer, and modify the given structures to draw the resulting products.

hello your question has some missing data attached below is the complete question.

Explanation:

Attached below is the mechanism for proton transfer

a) HBr

H₃O + Br⁻

b) attached below

c) attached below

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
