alkane

IPA: //ˈæl.keɪn//

KK: /ˈæl.keɪn/

noun

Definition: A type of chemical compound that consists only of carbon and hydrogen atoms, where the carbon atoms are connected by single bonds. These compounds are saturated, meaning they contain the maximum number of hydrogen atoms possible for the number of carbon atoms.

Example: Methane is the simplest alkane, consisting of one carbon atom and four hydrogen atoms.

alkene

IPA: //ælˈkiːn//

KK: /ælˈkiːn/

noun

Definition: A type of chemical compound that consists of carbon and hydrogen atoms, characterized by having at least one double bond between carbon atoms. These compounds are part of a larger group of hydrocarbons and are known for being unsaturated.

Example: Ethylene is the simplest alkene, consisting of two carbon atoms connected by a double bond.

alkoxide

IPA: /ˈæl.kəʊk.saɪd/

KK: /ˈæl.kəʊk.saɪd/

noun

Definition: A type of chemical compound that comes from an alcohol, where a hydrogen atom is replaced by a metal or another positively charged particle.

alkoxy

IPA: //ælˈkɒksi//

KK: /ælˈkɒksi/

adjective

Definition: Relating to a specific type of chemical group that includes an alkyl part connected to an oxygen atom.

Example: The chemist synthesized a new compound with an alkoxy group to enhance its solubility.

noun

Definition: A type of chemical group that consists of an oxygen atom connected to an alkyl group, which is a group of carbon and hydrogen atoms. This group can act as a part of larger molecules in chemistry.

Example: The chemist used an alkoxy group to modify the compound's properties.

alkyd

IPA: /ˈæl.kɪd/

KK: /ˈæl.kɪd/

noun

Definition: A type of strong, synthetic material made from glycerol and phthalic anhydride, commonly used in paints and coatings.

alkylated

IPA: /ˈæl.kɪ.leɪ.tɪd/

KK: /ˈæl.kɪ.leɪ.tɪd/

adjective

Definition: This term describes something that has been changed or altered by a chemical process where an alkyl group is added to a molecule.

Example: The alkylated compounds are often used in various chemical reactions.

verb

Definition: To add an alkyl group to a molecule, often in a chemical reaction.

Example: The compound was alkylated to enhance its reactivity.

alkylation

IPA: //ˌæl.kɪˈleɪ.ʃən//

KK: /ˌæl.kɪˈleɪ.ʃən/

noun

Definition: A process where a specific group of atoms, known as an alkyl group, is added to a chemical compound. This is often done to change the properties of the compound, such as making fuels more effective.
