Ethanethiol is the organic compound with the formula CH3CH2SH. It consists of an ethyl group, CH3CH2, abbreviated Et, attached to a thiol group, SH, and the entire molecule is often abbreviated EtSH.he compound is structurally similar to ethanol by replacement of O by S. This change leads to many different properties, the most infamous of which is the strong odour of EtSH. Ethanethiol is also more volatile than ethanol due to its diminished ability to engage in hydrogen bonding.
R-CH3 is an organic composite obtained starting from methane (CH4) and substituting one of the hydrogen atoms with an organic radical, generally indicated with R. Frequently t â¦ he functional group-CH3 is also called methil group.mportant examples are acetic acid, where R is the acid group COOH, so that the acetic acid has molecular formula CH3COOH and the methanamine, where the functional group is the amine group (NH2) so that the molecular formula results to be CH3NH2. 1 person found this useful.
