Which of the following is a Bronsted-Lowry base? Select one: CHa b. HCN NH3 d. Clz None of the above are Bronsted-Lowry bases<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is c. NH3<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The Bronsted-Lowry definition of acids and bases is based on proton (H+) transfer. According to this theory:<\/p>\n\n\n\n

    \n
  • A Bronsted-Lowry acid<\/strong> is a substance that donates a proton<\/strong> (H+).<\/li>\n\n\n\n
  • A Bronsted-Lowry base<\/strong> is a substance that accepts a proton<\/strong> (H+).<\/li>\n<\/ul>\n\n\n\n

    Let’s break down each of the options:<\/p>\n\n\n\n

      \n
    1. CH\u2084 (Methane)<\/strong>: This molecule is not a Bronsted-Lowry base. It neither donates nor accepts protons. Methane is chemically stable and does not readily participate in proton transfer.<\/li>\n\n\n\n
    2. HCN (Hydrogen Cyanide)<\/strong>: This molecule contains a hydrogen atom, but it behaves as an acid<\/strong> under Bronsted-Lowry theory, not a base. It can donate a proton (H\u207a) to form the cyanide ion (CN\u207b). Therefore, it is a Bronsted-Lowry acid, not a base.<\/li>\n\n\n\n
    3. NH\u2083 (Ammonia)<\/strong>: Ammonia is a Bronsted-Lowry base because it has a lone pair of electrons on the nitrogen atom. It can accept a proton (H\u207a) to form NH\u2084\u207a (ammonium ion). In aqueous solutions, ammonia readily accepts protons to form ammonium ions.<\/li>\n\n\n\n
    4. Cl\u2082 (Chlorine gas)<\/strong>: Chlorine gas does not have the ability to accept or donate protons. It is neither a Bronsted-Lowry acid nor a base. Chlorine typically participates in redox reactions, but not proton transfer.<\/li>\n<\/ol>\n\n\n\n

      Therefore, NH\u2083<\/strong> is the only substance that qualifies as a Bronsted-Lowry base in this list, as it can accept a proton.<\/p>\n\n\n\n

      In summary, ammonia (NH\u2083) is a Bronsted-Lowry base because it can accept a proton to form NH\u2084\u207a, which makes it fit the base definition in this theory.<\/p>\n\n\n\n
