  2. Benzoyl group - Wikipedia

    en.wikipedia.org/wiki/Benzoyl_group

    The benzoyl functional group.. In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen.

  3. Benzoic acid - Wikipedia

    en.wikipedia.org/wiki/Benzoic_acid

    Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...

  4. Benzoyl peroxide - Wikipedia

    en.wikipedia.org/wiki/Benzoyl_peroxide

    Benzoyl peroxide is a chemical compound (specifically, an organic peroxide) with structural formula (C 6 H 5 −C(=O)O−) 2, often abbreviated as (BzO) 2.In terms of its structure, the molecule can be described as two benzoyl (C 6 H 5 −C(=O)−, Bz) groups connected by a peroxide (−O−O−).

  5. Benzyl group - Wikipedia

    en.wikipedia.org/wiki/Benzyl_group

    The benzyl cation or phenylcarbenium ion is the carbocation with formula C 6 H 5 CH + 2; the benzyl anion or phenylmethanide ion is the carbanion with the formula C 6 H 5 CH − 2. None of these species can be formed in significant amounts in the solution phase under normal conditions, but they are useful referents for discussion of reaction ...

  6. Benzylic activation in tricarbonyl(arene)chromium complexes

    en.wikipedia.org/wiki/Benzylic_activation_in_tri...

    Benzylic anions of chromium arene complexes exhibit similar reactivity to cations. They are also conformationally restricted and undergo substitution reactions with retention of stereochemistry at the benzylic carbon. In the example below, complexation of the pyridine nitrogen to lithium is essential for high stereoselectivity. [1]

  7. Chemical drain cleaners - Wikipedia

    en.wikipedia.org/wiki/Chemical_drain_cleaners

    Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats. Drain cleaners can also contain aluminum, which reacts with sodium hydroxide to produce bubbles of hydrogen gas that help to break up the clog. [11]

  8. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...

  9. Benzoyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzoyl_chloride

    Benzoyl chloride, also known as benzenecarbonyl chloride, is an organochlorine compound with the formula C 7 H 5 ClO.It is a colourless, fuming liquid with an irritating odour, and consists of a benzene ring (C 6 H 6) with an acyl chloride (−C(=O)Cl) substituent.
