  2. N-Bromosuccinimide - Wikipedia

    en.wikipedia.org/wiki/N-Bromosuccinimide

    N-Bromosuccinimide or NBS is a chemical reagent used in radical substitution, electrophilic addition, and electrophilic substitution reactions in organic chemistry.

    The solution was stirred at room temperature for 30 minutes and then was heated at 50° for 4 hours. The resultant alkenylalane was cooled to –30°, diluted with 15 mL of dry ether, and treated with 5.35 g (30.1 mmol) of N-bromosuccinimide while keeping the temperature below –15°.

  4. Wohl–Ziegler bromination - Wikipedia

    en.wikipedia.org/wiki/Wohl–Ziegler_bromination

    The Wohl–Ziegler reaction [1] [2] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N-bromosuccinimide and a radical initiator. [3] Best yields are achieved with N-bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [4] [5]

  5. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...

    en.wikipedia.org/wiki/Bromine

    At room temperature, bromine trifluoride (BrF 3) is a straw-coloured liquid. It may be formed by directly fluorinating bromine at room temperature and is purified through distillation. It reacts violently with water and explodes on contact with flammable materials, but is a less powerful fluorinating reagent than chlorine trifluoride.
