Write the complete mechanism of bromination of benzaldehyde by a mixture of hydrobromic acid and potassium bromate in acetic acid. Consider bromination at the 4 and 3 position (para and meta), and explain, by showing the relevant resonance structures, why bromination preferentially takes place at the meta position.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
