Benzocaine: Base<\/strong><br>Benzocaine is a weak base. It is an ester of the amino acid para-aminobenzoic acid, with an amine group in its structure. The presence of the amine group (\u2013NH2) contributes basic properties, as amines tend to accept protons (H+) in a solution. The nitrogen atom in the amine group has a lone pair of electrons, allowing it to accept a proton, hence acting as a base. The ester group does not significantly alter this basicity. However, since benzocaine is a weak base, its ability to accept protons is limited, making it a weak base in aqueous solutions.<\/p>\n\n\n\n<p><strong>b. Biphenyl: Neutral<\/strong><br>Biphenyl is a neutral compound. It consists of two benzene rings connected by a single bond, and its structure does not contain any functional groups that would impart acidic or basic properties. Benzene rings are relatively non-polar and do not have groups that would either donate or accept protons in a typical acid-base reaction. As a result, biphenyl does not exhibit acidic or basic behavior in water and is classified as neutral.<\/p>\n\n\n\n<p><strong>c. Trans-cinnamic acid: Acid<\/strong><br>Trans-cinnamic acid is an organic acid. The carboxyl group (\u2013COOH) in cinnamic acid is the defining feature of its acidic behavior. The carboxyl group can donate a proton (H+) due to the presence of the electron-withdrawing carbonyl group (C=O) adjacent to the hydroxyl group (\u2013OH), making it a weak acid. In water, cinnamic acid dissociates partially, releasing H+ ions and acting as an acid. Its acidity is moderate compared to strong acids like HCl, but it is definitely more acidic than a neutral compound like biphenyl or a base like benzocaine.<\/p>\n\n\n\n<p><strong>Summary:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Benzocaine<\/strong> is a weak base due to the presence of an amine group.<\/li>\n\n\n\n<li><strong>Biphenyl<\/strong> is neutral because it lacks functional groups that would donate or accept protons.<\/li>\n\n\n\n<li><strong>Trans-cinnamic acid<\/strong> is an acid because it contains a carboxyl group that can donate a proton.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Identify the following compounds as Acid, Base or Neutral. a.
