Solution Verified by Toppr Correct option is C) The reaction mechanism as given in the figure shows that its a electrophilic substitution reaction where :CCl 2 is the electrophile. The reaction between phenol and chloroform in the presence of aqueous NaOH is electrophilic substitution reaction Video Explanation

Chloroform was one of the first inhaled anesthetics to be used during surgery, but it is not used for anesthesia today. Nearly all the chloroform made in the United States today is used to make other chemicals, but some is sold or traded to other countries. We also import chloroform.

which of the following mixtures will show a positive deviation from Raoult’s. law? (i) Methanol and acetone. (ii) Chloroform and acetone. (iii) Nitric acid and water. (iv) Phenol and aniline. Solution: Option (i) is the answer. 8. Colligative properties depend on _____. (i) the nature of the solute particles dissolved in the solution.

1-13 of 13 Products Grade Quantity Boiling Point Molecular Weight (g/mol) Percent Purity Chloroform, ACS, 99.8+%, Thermo Scientific Chemicals Thermo Scientific Chemicals Chloroform is suitable for pesticide analysis, environmental and GC analysis. It is a commonly used laboratory solvent. It was previously used as an anesthetic.

Chloroform is a colorless liquid with the chemical formula CHCl 3 and a common organic solvent. This compound is obtained by replacing three hydrogen atoms of an alkane with three halogen atoms. It quickly evaporates into a gas and can harm the eyes, skin, liver, kidneys, and nervous system. Chloroform exposure can potentially lead to cancer.

1. Chloroform is used as an anaesthetic in surgery by adding \ (30\% \) ether to Chloroform. 2. It is used as a solvent of oil, wax, fat, rubber etc. 3. In the laboratory as solvent and reagent. 4. In the manufacture of some useful organic compounds, such as chloretone, chloropicrin etc. 5.

It takes up to 4 hours before you can feel the effects of this medication, so typically, you should apply it at least 4 hours before you need it. The effects of a single scopolamine (Transderm Scop) patch lasts up to 3 days. Common side effects of this medication include dry mouth, sleepiness, and dizziness.

phenol chloroform in the presence of excess na is here we have a four option substitution reaction electrophilic addition reaction substitution reaction and addition reaction reaction so here phenol reacts with chloroform in the presence of alkalis at 40 K the hydrolysis of resulting product give to hydroxybenzaldehyde telephonic acid and the re.

When chloroform is left open in air in the presence of sunlight, it undergoes oxidation releasing a poisonous and toxic gas, phosgene alongwith hydrochloric acid.CHCl3 + [O] → COCl2Phosgene + HCl

The present work investigated the autoxidation reaction of p-toluenediamine (PTD) - a precursor - widely used in permanent hair dyeing formulation, under experimental conditions close to the hair dyeing process (oxygen and/or peroxide in ammoniacal medium), by chromatographic and spectroscopic techniques.

Oxidation of chloroform by oxygen in the air can generate phosgene, COCl 2, which was used as a chemical weapon during the first world war. Phosgene, although a gas at room temperature, readily dissolves in chloroform, where it remains until it is chemically treated for removal.
