Which of the following improperly describes the physical property of an alkyne?
- a)Relatively non-polar
- b)Insoluble in alcohols and ethers
- c)Less dense than water
- d)Nearly insoluble in water
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Which of the following improperly describes the physical property of a...
Alkynes are generally nonpolar molecules with little solubility in polar solvents, such as water. Solubility in nonpolar solvents, such as ether and acetone, is extensive. Like the alkanes and alkenes, alkynes of four or fewer carbon atoms tend to be gases.

Explanation:
An alkyne is a hydrocarbon compound that contains a carbon-carbon triple bond. It is characterized by its unique physical and chemical properties. Let's analyze each option to determine which one improperly describes the physical property of an alkyne.
a) Relatively non-polar:
Alkynes are relatively non-polar molecules because the electronegativity difference between carbon and hydrogen is small. This means that the electron density is evenly distributed throughout the molecule, resulting in a non-polar nature. Therefore, option 'a' is a correct description of the physical property of an alkyne.
b) Insoluble in alcohols and ethers:
This option improperly describes the physical property of an alkyne. Alkynes are generally soluble in alcohols and ethers due to the presence of similar non-polar characteristics. Alcohols and ethers are also non-polar solvents, allowing for dissolution of alkynes. Therefore, option 'b' is incorrect.
c) Less dense than water:
Alkynes are less dense than water because they have a lower molecular weight compared to water. The lower density allows them to float on the surface of water. Therefore, option 'c' is a correct description of the physical property of an alkyne.
d) Nearly insoluble in water:
Alkynes are nearly insoluble in water because water is a polar solvent, while alkynes are non-polar compounds. The polar nature of water prevents effective solvation of alkynes, resulting in low solubility. Therefore, option 'd' is a correct description of the physical property of an alkyne.
In conclusion, the option that improperly describes the physical property of an alkyne is 'b) Insoluble in alcohols and ethers'. Alkynes are generally soluble in alcohols and ethers due to their non-polar nature.
