Answer:
The boiling point of 1-chlorobutane is substantially lower than that of 1-butanol
Explanation:
Fractional distillation is a separation process based on difference in boiling point of two compounds.
1-chlorobutane is a polar aprotic molecule due to presence of polar C-Cl bond. Hence dipole-dipole intermolecular force exists in 1-chlorobutane as a major force.
1-butanol is a polar protic molecule. Hence dipole-dipole force along with hydrogen bonding exist in 1-butanol.
Therefore intermolecular force is stronger in 1-butanol as compared to 1-chlorobutane.
So, boiling point of 1-butanol is much higher than 1-chlorobutane.
Hence mixture of 1-chlorobutane and 1-butanol can be separated by fractional distillation based on difference in boiling point.
So, option (D) is correct.
Contains only Carbon and Hydrogen.
(3) CH3CH3
The answer is Caverns
as Caverns of limestone is a natural cavity, which forms in the subsurface of the earth by the effect of acidic groundwater and underground water (like rivers) making the limestone dissolve by time and leaves this cavity. which increase and grow up with time.
and there are many structures which form in this caverns ex :
(Speleothem, Stalactite, Flowstone, Stalagmite, Helictite)
burns is a chemical property.
Answer: Option (a) is the correct answer.
Explanation:
A chair is a solid substance and it is known that particles in a solid are closely held together by strong intermolecular forces of attraction.
Therefore, solids are rigid and have a definite shape.
Thus, we can conclude that the chair in which you are currently sitting retain its same shape over time because the particles of the chair are strongly held together.
