    (ch 3) 3 coh + hcl → (ch 3) 3 ccl + h 2 o Because tert -butanol is a tertiary alcohol, the relative stability of the tert -butyl carbocation in the step 2 allows the S N 1 mechanism to be followed, whereas a primary alcohol would follow an S N 2 mechanism.

    Molar mass: 92.57 g·mol −1 Appearance Colourless liquid Density: 877 mg mL −1: ... Isobutyl chloride (1-chloro-2-methylpropane) is an organochlorine compound.

  4. Mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrometry

    Ion mobility spectrometry-mass spectrometry (IMS/MS or IMMS) is a technique where ions are first separated by drift time through some neutral gas under an applied electrical potential gradient before being introduced into a mass spectrometer. [43] Drift time is a measure of the collisional cross section relative to the charge of the ion.

  5. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    [1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...

  6. tert-Amyl chloride - Wikipedia

    en.wikipedia.org/wiki/Tert-Amyl_chloride

    tert-Amyl chloride (2-methyl-2-butyl chloride) is an alkyl chloride used for flavoring and odorizing. [2] At room temperature, it is a colorless liquid with an unpleasant odor. It is an isomer of 1-chloropentane ( n -amyl chloride).

  7. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...

  8. Mass chromatogram - Wikipedia

    en.wikipedia.org/wiki/Mass_chromatogram

    A mass chromatogram is a representation of mass spectrometry data as a chromatogram, where the x-axis represents time and the y-axis represents signal intensity. [1] The source data contains mass information; however, it is not graphically represented in a mass chromatogram in favor of visualizing signal intensity versus time.

  9. Gas chromatography–mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Gas_chromatography–mass...

    For the analysis of volatile compounds, a purge and trap (P&T) concentrator system may be used to introduce samples. The target analytes are extracted by mixing the sample with water and purge with inert gas (e.g. Nitrogen gas) into an airtight chamber, this is known as purging or sparging.
