Hi there! I know about those topics! What do you need help with?
Add a coefficient 2 before H2O and a 2 before SO2.
Answer:
The drawing of the mechanism and the organic product is shown below.
Explanation:
Alkynes react with bromine to form a dihaloalkene (with an equivalent of the halogen) or a tetrahaloalkane derivative (with two equivalents of the halogen), which is this case. The triple bond adds two halogen molecules as shown in the drawing, an anti addition occurring.
We Know, Velocity of light = frequency * wavelength
frequency = velocity/wavelength
f = 3 * 10⁸ / 6.50 * 10⁻⁷
f = 4.61 Hertz
So, your final answer is 4.61 Hz
Hope this helps!
