p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol, is an organic compound classified as a diol and a terpenoid. It is colorless. Its name reflects the hydrocarbon backbone, which is that of p-menthane. A total of eight stereoisomers are possible, based on the three stereocenters of the ring. Depending on the source ...
A similar process can also be used to prevent self-condensation between two ketones. In this case, however, the base used needs to be more powerful. A common base used is Lithium diisopropyl amide (LDA). Here it is used in order to perform the crossed condensation between acetone and cyclohexanone. [3]
The biopsychological theory of personality is a model of the general biological processes relevant for human psychology, behavior, and personality. The model, proposed by research psychologist Jeffrey Alan Gray in 1970, is well-supported by subsequent research and has general acceptance among professionals.
3,3-Dimethylhexane is a colourless, odourless liquid, chemical compound in the family of hydrocarbons which has a formula of C 8 H 18. It is an isomer of octane , where two methylene hydrogens at the third position in a hexane molecule have been replaced with two methyl groups.
