Its sodium salt can be prepared from the chloride: [6] (C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. The use of tritylsodium as a strong, non-nucleophilic base has been eclipsed by the popularization of butyllithium and related strong bases. The unmodified anion is red, and can be used as an indicator in acid–base titrations. Derived ...
Triphenylmethanol features three phenyl (Ph) rings and an alcohol group bound to a central tetrahedral carbon atom. All three C–Ph bonds are typical of sp 3-sp 2 carbon-carbon bonds with lengths of approximately 1.47 Å, while the C–O bond length is approximately 1.42 Å.
Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2 , and ethanol is likely to be the best solvent of those tabulated.
3-Methylheptane is a branched alkane isomeric to octane. Its structural formula is CH 3 CH 2 CH(CH 3)CH 2 CH 2 CH 2 CH 3. It has one stereocenter. Its refractive index is 1.398 (20 °C, D). [citation needed]
2-Methylheptane is a branched-chain alkane and an isomer of octane. It is an heptane molecule with a methyl group attached to its second atom. It is a flammable colorless liquid used as fuel. [2] If the standard definition of the prefix "iso-" is strictly used then 2-methylheptane can be called "Isooctane".
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .
