Chlorine, bromine, and iodine are all elements in the halogen group of the periodic table. They share many similar properties due to their similar electron configurations.
Let's evaluate each statement:
A. dissolve in alkalis: This is generally true. Halogens can react with alkalis, but the reaction depends on the specific halogen and alkali involved.
B. react violently with hydrogen without heating: This is not necessarily true. While halogens do react with hydrogen to form hydrogen halides, the reaction may not always be violent and may require heating, especially in the case of iodine.
C. displace each other from solutions of their salts: This is true. This is known as the halogen displacement reaction. A more reactive halogen can displace a less reactive halogen from a solution of its salts.
D. are gases: This is not true. At room temperature, chlorine is a gas, bromine is a liquid, and iodine is a solid.
E. are liquids: This is also not true. As mentioned above, these halogens exist in different states at room temperature.
So, the correct answer is **C. displace each other from solutions of their salts**. This is a characteristic property of halogens.
The answer is A and not C according to what some of you are saying.
This is their order of reactivity Chlorine> Bromine> Iodine.
So thus goes to show that Chlorine can displace Bromine and Iodine, Bromine can displace only Iodine & Iodine can not displace any of them.
THE ANSWER IS A :THEY ALL REACT WITH ALKALIS TO WATER SALT AND EITHER OXIDE OF THE HALOGENS
The correct option is:
C. displace each other from solutions of their salts
Chlorine, bromine, and iodine are all halogens and exhibit similar chemical properties. They can displace each other from solutions of their salts because they have a similar reactivity trend: chlorine is more reactive than bromine, which is more reactive than iodine. So, a more reactive halogen can displace a less reactive one from its salt solution.
this question is another yeah you people choosed option C what is even wrong with myschool sometimes
correct answer is C. All three of these halogens (chlorine, bromine, and iodine) are pretty feisty, so they'll displace each other from solutions of their salts.
option c is not correct reason iodine cannot dsisplace bromine and bromine cannot displace iodine but A is the right answer halogens react with alkali they are correct
