27 paź 2022 · NaOH and KOH are ionic compounds that contain OH – ions. Alcohols are covalent molecules; the –OH group in an alcohol molecule is attached to a carbon atom by a covalent bond. Ethanol, CH 3 CH 2 OH, also called ethyl alcohol, is a particularly important alcohol for human use.
Naming Ethers. Ethers are compounds having two alkyl or aryl groups bonded to an oxygen atom, as in the formula R 1 –O–R 2. The ether functional group does not have a characteristic IUPAC nomenclature suffix, so it is necessary to designate it as a substituent.
This online quiz is intended to give you extra practice in concepts related to introductory organic nomenclature, including naming compounds and identifying functional groups from diagrams.

The IUPAC naming process of naming ethers involves separately naming each of the two groups attached to the oxygen atom. The group that has the longest continuous carbon chain is considered the parent chain and is named accordingly.
Ethers are stable to bases, but acidic conditions leads to the protonation of the ether oxygen, which then can undergo substitution reactions. The alcohol produced reacts to generate a second molecule of alkyl halide.
Alcohols are usually named by the first procedure and are designated by an ol suffix, as in ethanol, CH3CH2OH (note that a locator number is not needed on a two-carbon chain). On longer chains the location of the hydroxyl group determines chain numbering. For example: (CH3)2C=CHCH(OH)CH3 is 4-methyl-3-penten-2-ol.
26 wrz 2022 · Testing an Alcohol. Alcohols can be classified as either primary, secondary or tertiary, depending on the placement of the -OH group; Primary and secondary alcohols can both be oxidised, but tertiary alcohols cannot; To test for the alcohol functional group, add a small amount (1 cm 3) of the substance to a test tube using a pipette
