What is the difference between alkanes and alkenes?

• Alkanes are solid at room temperature, while alkenes are liquid.

• Alkanes have only single bonds, while alkenes have at least one double bond.

• Alkanes have at least one double bond, while alkenes have only single bonds.

• Alkanes and alkenes are the same and can be used interchangeably.

What is the general formula for alkynes?

What are substituted hydrocarbons?

• Synthetic compounds with replaced nitrogen atoms

• Organic compounds with replaced hydrogen atoms

• Inorganic compounds with replaced oxygen atoms

• Metallic compounds with replaced carbon atoms

What is the hydroxyl group and what is its significance in organic chemistry?

• A functional group consisting of an oxygen atom bonded to a hydrogen atom, significant in organic chemistry.

• A type of polymer used in organic chemistry experiments

• A type of gas that is commonly found in organic compounds

• A type of metal used in organic chemistry reactions

What is the carboxyl group and where is it commonly found?

• Commonly found in the Earth's atmosphere

• Inorganic compounds such as metals and minerals

• Found in the nucleus of a cell

• Organic compounds such as carboxylic acids and amino acids

What is the amino group and what role does it play in organic compounds?

• It is a type of sugar found in plants and has no role in organic compounds

• It is a type of metal ion that acts as a catalyst in organic compounds

• It is a type of hydrocarbon that provides color to organic compounds

• It is a functional group that contains a nitrogen atom bonded to hydrogen atoms and plays a crucial role in organic compounds.

What is an amino acid and how is it related to hydrocarbons?

• Amino acids are a type of mineral and have no connection to hydrocarbons.

• Amino acids are inorganic compounds that do not contain carbon or hydrogen atoms.

• Amino acids are related to hydrocarbons because they are used as fuel for vehicles.

• Amino acids are organic compounds that contain both an amine group and a carboxyl group. They are related to hydrocarbons because they contain carbon and hydrogen atoms in their structure.
