11. A pair of carboxylic acid molecules are held together by two hydrogen bond but in oder cases only one H-bond present.
2. Dipolar ion
3. LiAlH4 / H2O
4.Electrophilic substitution reaction (chlorination)
1. What characteristic of a carboxylic acid gives the molecule a much higher boiling point than many other molecules of similar molecular weight?
2. The carboxyl group (R-COOH or R-CO2H) is one of the two functional groups that is present on the building blocks of protein, amino acids. The second functional group on an amino acid is the amine group (R-NH2) and this along with the carboxyl group allows an amino acid to exist as a what?
3. A carboxylic acid can be used to derive many different organic molecules. For example, a primary alcohol such as ethanol can be synthesized by reducing a carboxylic acid. What is the essential reducing agent used in this organic reaction?
4. What type of reaction has taken place if chlorobenzene (C6H5Cl) has been synthesised from an initial molecule of benzene (C6H6)?
