Questions Related to carbon tetrachloride

Multiple choice carbon tetrachloride ddt preparation of haloalkanes halogen derivatives
Carbon tetrachloride is inflammable.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbon tetrachloride $\displaystyle (CCl _4)$ is not inflammable.
Hence, the given statement is false.

Note:
Carbon tetrachloride $\displaystyle (CCl _4)$ is poisionous and water insoluble. It is soluble in ethanol and ether.

Multiple choice carbon tetrachloride ddt preparation of haloalkanes halogen derivatives

What happens when $C{Cl} _{4}$ is treated with $Ag{NO} _{3}$ solution?

  1. ${NO} _{2}$ is evolved
  2. A white precipitate of $AgCl$ is formed
  3. $C{Cl} _{4}$ will dissolve in $Ag{NO} _{3}$ solution

  4. No reaction
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$C{Cl} _{4}$ is a covalent compound, so it does not react with $Ag{NO} _{3}$

Multiple choice carbon tetrachloride ddt preparation of haloalkanes halogen derivatives
State whether the statement is true or false
Carbon tetrachloride burns in the air when lighted to give phosgene.

  1. The statement is true

  2. The statement is false

  3. Neither

  4. Carbon tetrachloride rarely burns in the air when lighted to give phosgene.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon tetrachloride is non-inflammable gas. It does not undergo combustion reaction. Hence, it does not burns in air when ignited to give phosgene. Phosgene is rather formed from chloroform.

Multiple choice carbon tetrachloride ddt preparation of haloalkanes halogen derivatives

The halo compound of methane used as fire extinguisher under the name Pyrene is:

  1. $CHCl _{3}$
  2. $CH _{2}Cl _{2}$
  3. $CCl _{2}F _{2}$
  4. $CCl _{4}$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Carbon tetrachloride $CCl _4$, is widely used in fire extinguishers. The liquid vaporized and extinguished the flames by inhibiting the chemical chain reaction of the combustion process.


In 1910, The Pyrene Manufacturing Company of Delaware filed a patent to use carbon tetrachloride to extinguish fires under the name $Pyrene$.

$CCl _4$ is used as fire extinguisher because:

  1. its melting point is high.

  2. It forms covalent bond.

  3. Its boiling point is low.

  4. It gives incombustible vapours.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Its use in the home as a spot remover should be avoided because of its poisonous nature.
Because its vapours (incombustible vapours) are denser than air which leads to a smoother flame.
Hence option D is correct.

Multiple choice carbon tetrachloride ddt preparation of haloalkanes halogen derivatives

Which of the following are polyhalogen compounds?

  1. Dichloromethane

  2. Chloroform

  3. Tetrachloromethane

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dichloromethane is $CH _2Cl _2$.
Chloroform is $CHCl _3$.
Tetrachloromethane is $CCl _4$. 
All contain more than one halogen, so, they are all polyhalogen compounds.
