How does anisole react with Br2 in CS2?
How does anisole react with Br2 in CS2?
Answer. Anisole reacts with Br2 in the presence of CS2 as solvent to give: (4) A mixture of 2-Bromoanisole and 4- Bromoanisole. – When anisole is reacted with bromine in the solvents of low polarity (like CS2), then the bromination takes place at ortho and para positions.
Which is the correct product formed from the bromination of nitrobenzene?
The nitro group is meta directing and ortho-para deactivating group. Thus bromination of nitrobenzene gives m-bromonitrobenzene as a major product.
Why glacial acetic acid is used in bromination of acetanilide?
In order to obtain monobromo aniline,reaction is carried out in presence of acetic acid. In glacial acetic acid,bromine is ionised to lesser extent and hence relatively less number of bromonium ions are formed. Thus interference of water is ceased.
What type of reaction is bromination of acetanilide?
Bromination of acetanilide gives para brominated acetanilide mainly, because amino group of acetanilide is protected by acetyl group. Reaction: Mechanism: Bromination is an electrophilic substitution reaction on an aromatic ring.
What is glacial acetic acid used for?
Glacial acetic acid is an excellent polar protic solvent, as noted above. It is frequently used as a solvent for recrystallization to purify organic compounds. Acetic acid is used as a solvent in the production of terephthalic acid (TPA), the raw material for polyethylene terephthalate (PET).
How dangerous is acetic acid?
Acetic acid can be a hazardous chemical if not used in a safe and appropriate manner. This liquid is highly corrosive to the skin and eyes and, because of this, must be handled with extreme care. Acetic acid can also be damaging to the internal organs if ingested or in the case of vapor inhalation.
Is glacial acetic acid a strong acid?
Similar to the German name Eisessig (ice-vinegar), the word “glacial” is derived from the ice-like crystals that form at 16.6°C (61.9°F), slightly below room temperature. Although classified as a weak acid, glacial acetic acid is a corrosive poison that can cause injury or death when human tissue is exposed to it.
What is difference between acetic acid and glacial acetic acid?
Acetic acid is a solution of acetic acid and water. Glacial acetic acid is nothing but the concentrated form of acetic acid solution. Acetic acid contains more water and is in its diluted form. Glacial acetic acid has less than 1% of water content and is concentrated.
Is acetic acid a weak or strong acid?
A weak acid is an acid that ionizes only slightly in an aqueous solution. Acetic acid (found in vinegar) is a very common weak acid.
