  2. Chlorine - Wikipedia

    en.wikipedia.org/wiki/Chlorine

    Corresponding to periodic trends, it is intermediate in electronegativity between fluorine and bromine (F: 3.98, Cl: 3.16, Br: 2.96, I: 2.66), and is less reactive than fluorine and more reactive than bromine. It is also a weaker oxidising agent than fluorine, but a stronger one than bromine.

    en.wikipedia.org/wiki/Color_of_chemicals

    The Colour bond more than covalent more will the colour intensity...!! All atoms and molecules are capable of absorbing and releasing energy in the form of photons, accompanied by a change of quantum state. The amount of energy absorbed or released is the difference between the energies of the two quantum states.

  4. Bromine - Wikipedia

    en.wikipedia.org/wiki/Bromine

    Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine.

    A variety of food colorings, added to beakers of water. Food coloring, color additive or colorant is any dye, pigment, or substance that imparts color when it is added to food or beverages. Colorants can be supplied as liquids, powders, gels, or pastes. Food coloring is commonly used in commercial products and in domestic cooking.

    en.wikipedia.org/wiki/Interhalogen

    Chlorine trifluoride has a boiling point of −12 °C. Bromine trifluoride has a boiling point of 127 °C and is a liquid at room temperature. Iodine trichloride melts at 101 °C. [1] Most interhalogens are covalent gases. Some interhalogens, especially those containing bromine, are liquids, and most

  9. Reactivity–selectivity principle - Wikipedia

    en.wikipedia.org/wiki/Reactivity–selectivity...

    Whereas the relatively unreactive bromine reacts with 2-methylbutane predominantly to 2-bromo-2-methylbutane, the reaction with much more reactive chlorine results in a mixture of all four regioisomers. Another example of RSP can be found in the selectivity of the reaction of certain carbocations with azides and water.
