Organic Chemistry

What is isomerism in organic chemistry?

• Isomerism is when compounds have the same molecular formula but different physical properties.

• Isomerism is when compounds have different molecular formulas but the same structural arrangement.

• Isomerism is when compounds have the same molecular formula and the same structural arrangement.

• Isomerism in organic chemistry is when two or more compounds have the same molecular formula but different structural arrangements or spatial orientations of atoms.

How many types of isomerism are there?

• 4

• 5

• 2

• 3

What are functional groups in organic chemistry?

• Functional groups are inert groups of atoms within molecules.

• Functional groups have no impact on the chemical properties of molecules.

• Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

• Functional groups are only found in inorganic compounds.

Give an example of a functional group.

• Hydroxyl group (-OH)

• Phosphate group (-PO4)

• Carbonyl group (-C=O)

• Amino group (-NH2)

What is nomenclature in organic chemistry?

• Naming compounds based on the scientist who discovered them

• Randomly assigning names to organic compounds

• Systematic naming of organic compounds based on IUPAC rules.

• Using emojis to represent organic compounds

Why is nomenclature important in organic chemistry?

• Nomenclature provides a standardized way to name and identify organic compounds.

• Nomenclature is not important in organic chemistry

• Naming organic compounds is not necessary

• Organic compounds do not need to be identified

What is the IUPAC system used for in nomenclature?

• Naming organic compounds

• Classifying rocks in geology

• Describing chemical reactions

• Identifying elements in the periodic table

How do you name alkanes using IUPAC nomenclature?

• Ignore the longest carbon chain when naming alkanes

• Use Roman numerals to name alkanes

• Use IUPAC nomenclature to name alkanes by identifying the longest carbon chain, adding the appropriate prefix based on the number of carbons, and naming any substituents with prefixes and numbers.

• Name alkanes based on the number of hydrogen atoms

What is the general formula for alkanes?

• CnH2n

• CnH2n-2

• CnH2n+2

• CnH2n+3

Name the functional group present in alcohols.

• Hydroxyl group (-OH)

• Sulfhydryl group (-SH)

• Carbonyl group (-CO)

• Amino group (-NH2)
