What is B5H11? Important knowledge about B5H11.

  1. B5H11, also known as Pentaborane(11), is a chemical substance belonging to the borane group. It is generally known by the common name pentaborane. The molar mass of B5H11 is 61.83 g/mol. B5H11 consists of 5 boron atoms and 11 hydrogen atoms. It does not form ions due to its non-metallic properties.

  2. Properties of B5H11:
    2.1 Physical properties: Pentaborane is colorless, tasteless, odorless and has a neutral pH level. It has non-metallic properties and does not form ions.
    2.2 Chemical properties: Pentaborane is very stable and does not easily react with other substances. However, it can react with oxygen, strong oxidizing agents to produce water and boron trioxide.

  3. Chemical equation of B5H11: There are very few common chemical reactions of pentaborane due to its stability characteristic.

  4. Preparation of B5H11:
    4.1 Laboratory synthesis: B5H11 is usually produced from the reaction between diborane (B2H6) and boron trifluoride (BF3).
    4.2 Industrial synthesis: In the industry, B5H11 is produced by thermally decomposing diborane at a high temperature (about 200 degrees C).
