Why is bromination of phenol in water is trisubstituted but in CS2 is monosubstituted?

Posted by Pratistha Rawat 6 years, 2 months ago

Deeya Singh 6 years, 2 months ago

In water, phenol liberates H+ and forms phenoxide ion. This activates the Ortho and Para positions of phenol very much which leads to the formation of 2,4,6-Tribromophenol. Whereas nothing such happens when CS2 is used in bromination of phenol and only monosubstituted compound is formed.

•Solve as many past year questions as much as you can. •Try to focus on the type of questions which come. •Also, check out the pattern and trends in questions of each part(I and II) •Understand the way to solve similar type of questions because usually the pattern and sequences of the questions is similar. Like in Part-I Mathematics, the first question of each year is similar and the pattern to solve them is also similar. NOTE: The above are my personal experiences while solving KVPY-SX question papers. Hopefully it might help you! ?

Biomolecules are defined as any organic molecule present in a living cell which includes carbohydrates, proteins, fats etc. Each biomolecule is essential for body functions and manufactured within the body. They can vary in nature, type, and structure where some may be straight chains, some may be cyclic rings or both. Also, they can vary in physical properties such as water solubility, melting points.

Explain why chloroform uis not soluble in water although it is polar

Posted by Abhinav Saini 6 years, 2 months ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 6 years, 2 months ago

Chloroform is a slightly polar compound. But it cannot make any strong bond (like hydrogen bond) with water. Due to lack of strong interaction with water its solubility in water is very less.
Solubility of chloroform in water is 0.8g/100mL at 20⁰c

ANSWER

Explain why phenols having higher boiling point than that of alcohol

Posted by Aakanksha Yadav 6 years, 2 months ago

CBSE > Class 12 > Chemistry

1 answers

Sia ? 6 years, 2 months ago

Phenol has the higher boiling point about 181.7 °C, because in phenol the -Oh group is attached to an unsaturated carbon atom due to which it forms stronger hydrogen bonding than the alcohols and so phenol is more soluble in water and need more energy to break the H-bonds which increases its boiling point.
