Correct Lewis Structure for BH\u2083:<\/h3>\n\n\n\n

To draw the correct Lewis structure for borane (BH\u2083):<\/p>\n\n\n\n

    \n
  1. Place the boron (B) atom in the center since hydrogen (H) can form only one bond and cannot be the central atom.<\/li>\n\n\n\n
  2. Attach three hydrogen atoms to the boron atom using single bonds.<\/li>\n\n\n\n
  3. Do not<\/strong> add lone pairs to hydrogen, as each hydrogen only needs 2 electrons (1 bond).<\/li>\n\n\n\n
  4. Boron will have only 6 electrons (3 bonds), which is an exception to the octet rule.<\/li>\n<\/ol>\n\n\n\n

    Explanation<\/h3>\n\n\n\n
    The Lewis structure of BH\u2083 (borane) illustrates the bonding arrangement between boron and hydrogen atoms. BH\u2083 is a molecule composed of one boron (B) atom and three hydrogen (H) atoms. To draw the Lewis structure, we begin by determining the number of valence electrons:<\/p>\n\n\n\n
      \n
    • Boron (Group 13): 3 valence electrons<\/li>\n\n\n\n
    • Hydrogen (Group 1): 1 valence electron \u00d7 3 = 3<\/li>\n\n\n\n
    • Total = 3 (B) + 3 (H) = 6 valence electrons<\/strong><\/li>\n<\/ul>\n\n\n\n
      In the Lewis structure, the boron atom is placed at the center with three single bonds connecting it to three hydrogen atoms. Each single bond (B\u2013H) consists of 2 electrons. Thus, 3 bonds use all 6 available valence electrons.<\/p>\n\n\n\n
      Hydrogen atoms follow the duet rule<\/strong>, meaning they are stable with 2 electrons (1 bond). Each H atom in BH\u2083 forms a single bond with B, which satisfies this requirement.<\/p>\n\n\n\n
      Boron, however, is an exception to the octet rule<\/strong>. In BH\u2083, boron has only 6 electrons around it (3 single bonds), making it electron-deficient. It does not have a complete octet, but this is acceptable for boron compounds, especially in small molecules like BH\u2083.<\/p>\n\n\n\n
      This electron deficiency makes BH\u2083 highly reactive; it often acts as a Lewis acid<\/strong>, meaning it can accept a pair of electrons to complete its octet. In chemistry, BH\u2083 is often seen in reactions where it forms adducts with Lewis bases.<\/p>\n\n\n\n
      In summary, the Lewis structure for BH\u2083 is a simple molecule with three B\u2013H bonds and no lone pairs. It illustrates key concepts such as exceptions to the octet rule and the stability of hydrogen with only two electrons.<\/p>\n\n\n\n
