Gaaffii 1

Which one of the following is a colorless, flammable volatile liquid and miscible with non-polar solvents?

A.Methane
B.Methanol
C.Ethanol
D.Benzene

Deebii fi ibsa ilaalaa

Deebii: D Benzene

Maaliif

Benzene is a colorless, volatile, and flammable liquid. Being non-polar, it is immiscible with polar solvents like water but highly miscible with non-polar organic solvents.

Gaaffii 3

Which one of the following petroleum products is used as a solvent and in dry cleaning?

A.Diesel oil
B.Paraffin wax
C.Petroleum ether
D.kerosene

Deebii fi ibsa ilaalaa

Deebii: C Petroleum ether

Maaliif

Petroleum ether, with a relatively low boiling point range, is widely used as a non-polar solvent in laboratories and in the dry cleaning industry.

Gaaffii 4

Which one of the following is NOT TRUE about laboratory preparation of ethylene by dehydration of ethanol?

A.The collected ethylene gas in the experiment decolorizes alkaline K Mn O 4 .
B.Combustion of ethylene produces a non-luminous flame.
C.Concentrated sulphuric acid is used as a dehydrating agent.
D.The collected ethylene gas in the experiment decolorizes Br $_{2}$ in CC1 $_{4}$ .

Deebii fi ibsa ilaalaa

Deebii: B Combustion of ethylene produces a non-luminous flame.

Maaliif

Alkenes like ethylene have a high carbon-to-hydrogen ratio compared to alkanes, which causes them to burn with a luminous, yellow, and smoky flame due to incomplete combustion, rather than a non-luminous flame.

Gaaffii 5

Which one of the following is an essential nutrient of plants?

A.Potassium
B.Sodium
C.Lead
D.Aluminum

Deebii fi ibsa ilaalaa

Deebii: A Potassium

Maaliif

Potassium (K) is one of the three primary macronutrients (along with nitrogen and phosphorus) essential for healthy plant growth and development.

Gaaffii 6

In a kinetic experiment, a student placed crystals of iodine in a closed reaction vessel, introduced a given quantity of hydrogen gas, and collected data to calculate the rate of formation of hydrogen iodide. What would be the effect obtained on the rate of the reaction, if the student takes more amount of iodine from that used in the first experiment?

A.The rate of the reaction will be constant.
B.The formation of hydrogen iodide will be decreased.
C.It lowers the rate of the reaction.
D.It speeds up the rate of the reaction.

Deebii fi ibsa ilaalaa

Deebii: A The rate of the reaction will be constant.

Maaliif

Because iodine is present as a solid in this reaction, its concentration and activity are constant and independent of the amount added; thus, adding more solid iodine has no effect on the reaction rate.

Gaaffii 7

Which of the following CORRECTLY relates the vapor pressure of a liquid with its boiling point? Boiling point is

A.the temperature at which the kinetic energy of molecules is much less than the intermolecular force.
B.the temperature at which molecules present in the vapor phase go back to the liquid state.
C.the temperature at which the vapor pressure becomes equal to the external pressure.
D.the temperature at which all the three physical state co-exist.

Deebii fi ibsa ilaalaa

Deebii: C the temperature at which the vapor pressure becomes equal to the external pressure.

Maaliif

The boiling point of a liquid is defined as the temperature at which its vapor pressure becomes equal to the surrounding external atmospheric pressure.
