Historical Examples of alkyl
Hydrogen may be substituted in these chains by alkyl or aromatic groups.
The glyoxalines are basic in character, and the imide hydrogen is replaceable by metals and alkyl groups.
For instance, an alkyl may be substituted for the hydroxyl hydrogen in an alcohol molecule, when an ether results.
The influence of position of an alkyl in the aromatic bodies is well shown in ortho-, para- and meta-derivatives.
We may also notice that thio-ethers combine with alkyl iodides to form sulphine or sulphonium compounds, R3SI.
