Match the following characteristics of organic compounds with their descriptions:
Non-ionic Character = Do not give ionic reactions Similarity in Behaviour = Exemplified by the existence of homologous series Complexity of Organic Compounds = Large and structurally more complex molecules Isomerism = Different structural formulas for compounds with the same molecular formula
Match the following characteristics of organic compounds with their properties:
Rates of Organic Reactions = Slow reactions and low yields Solubility = Insoluble in water and dissolve readily in non-polar organic solvents Complexity of Organic Compounds = Large molecular masses ranging from a few thousands to a million Non-ionic Character = Result of being covalent compounds
Match the following properties of organic compounds with their descriptions:
Large and Structurally More Complex Molecules = Proteins with molecular masses ranging from a few thousands to a million Insolubility in Water = Dissolve readily in non-polar organic solvents Slow Rate of Reactions = Due to the molecular nature of organic compounds Isomerism = More than one compounds represented by the same molecular formula with different structural formulas
Match the following characteristics of organic compounds with their examples:
Starch Formula (C6H10O5)n = Example of a large and structurally complex organic molecule Proteins = Complex molecules with molecular masses ranging from a few thousands to a million Homologous Series = Exemplifies the similarity in behaviour between different organic compounds Isomerism = Phenomenon where different compounds have the same molecular formula but different structural formulas
What is isomerism and why is it a common phenomenon in organic compounds?
Isomerism is the phenomenon where more than one compound is represented by the same molecular formula but has different structural formulas. It is common in organic compounds due to the presence of carbon atoms that can form different arrangements or bonding patterns.
Explain the complexity of organic compounds and provide an example to illustrate it.
Organic molecules are usually large and structurally more complex. For example, starch has the formula (C6H10O5)n where n may be several thousands, and proteins are very complex molecules with molecular masses ranging from a few thousands to a million.
Why do organic compounds generally not give ionic reactions?
Organic compounds are generally covalent compounds, and therefore, do not give ionic reactions.
What are the typical solubility properties of organic compounds?
Most organic compounds are insoluble in water and dissolve readily in non-polar organic solvents, such as benzene and petroleum ether.
Explain the concept of isomerism in organic compounds and provide an example to illustrate it.
Isomerism is a phenomenon where different compounds have the same molecular formula but different structural formulas. An example is the isomerism between butane and isobutane.
Why are organic compounds generally covalent and do not give ionic reactions?
Organic compounds are generally covalent because they consist of carbon and hydrogen atoms bonded together through covalent bonds. As a result, they do not dissociate into ions and therefore do not give ionic reactions.
Describe the solubility properties of organic compounds and explain why they are generally insoluble in water but dissolve readily in non-polar organic solvents.
Most organic compounds are insoluble in water due to their non-polar nature, while they dissolve readily in non-polar organic solvents because like dissolves like. This is because non-polar solvents can effectively break the non-polar bonds in organic compounds.
What contributes to the structural complexity of organic molecules and provide an example to illustrate this complexity?
Organic molecules are structurally complex due to their large size and intricate arrangements of atoms. An example is starch, which has the formula (C6H10O5)n where n may be several thousands, demonstrating its structural complexity.
