Among given compounds Alkynes belong to a class of unsaturated hydrocarbons. The carbon atom in alkyne is sp hybridized. These unsaturated hydrocarbons have their own characteristic chemical properties.
Final answer:
A compound with a triple bond, like acetylene, is a molecule where three pairs of electrons are shared between two atoms. Acetylene contains a triple bond between its two carbon atoms. These bonds are strong, robust, and render unique properties to the compound.
Explanation:
A compound that contains a triple bond is a molecule in which three pairs of electrons are shared between two atoms, making it a very strong connection. An example of such a compound is acetylene (C2H2), which contains a triple bond between the two carbon atoms. The presence of triple bonds results in substances with unique properties when compared to compounds with only single or double bonds.
The triple bond in acetylene is formed by one sigma bond and two pi bonds. This means that acetylene is a more robust compound because of the strength of the triple bond. Additionally, molecules with triple bonds often have interesting chemical reactivities which make them important in various fields such as organic chemistry or industrial synthesis.

Given:
Distance of solvent front = 68 mm
Distance of unknown = 48 mm
To determine:
The rf value
Explanation:
The retention factor or the rf value is given by the ratio of distance traveled by the unknown to the distance traveled by the solvent front
RF = distance by unknown/distance by solvent
RF = 48/68 = 0.706
Ans: the RF value is 0.706
Final answer:
The Rf (Retention factor) value can be calculated using the given distances traveled by the solvent and the substance. The Rf value in this case is approximately 0.71.
Explanation:
The Rf value or Retention factor value in chromatography can be calculated with the given parameters of solvent front and the distance the substance travelled from the original spot. The formula to calculate the Rf value is: Rf = distance traveled by the substance / distance traveled by the solvent. So, in this case, it would be: Rf = 48mm / 68mm which is approximately 0.71.

The illuminance on a surface (E) is equal to the light intensity (I) divided by the square distance from the light source (d):
E = I ÷ d² [=] candela/ square meters = lux.
The unit of the illuminance is lux.
So, it is given:
E = 4 lux
I = 100 candelas
d = ?
If:
E = I ÷ d²
Then
d² = I ÷ E
⇒ d² = 100 ÷ 4
⇒ d² = 25
If we put both sides of the equation under the square root, then:
√d² = √25
⇒ d = 5 meters.
Therefore, the surface is 5 meters far from the light source.
