Detailed Solution: Question 16

"Lewis Acid is something that accepts a pair of electrons."

"A Lewis Base is something that donates a pair of electrons."

So Cl- would be a Lewis base.

NH3 is a Lewis Base.

BF3 is NOT a Lewis Base because it has an empty p orbital, this is a Lewis Acid.

C2H5OH is ethanol and that is a Lewis Base because the Oxygen has two lone pairs of electrons that it can donate.

The compound that is most reactive towards electrophilic nitration is:

Detailed Solution: Question 23

Electrophilic nitration involves attack of nitronium ion on benzene ring. The reactivity of benzene ring increases with increase in the electron density on it. The group which increase the electron density on the ring also increase the reactivity towards electrophilic substitution. These groups which show +I or +M effect like alkyl, alkoxy etc., release electrons towards benzene ring.

Conclusion:

Toluene is more reactive towards electrophilic nitration due to presence of electron donating methyl group.

JEE Main Chemistry Mock Test- 8 - Question 25

27 gm of Al react with excess of oxygen to give 4.95 gm of Al2O3, calculate % yield of reaction.


Detailed Solution: Question 25

Step 1: Write the balanced chemical equation for the reaction

The reaction between aluminum (Al) and oxygen (O₂) to form aluminum oxide (Al₂O₃) is:

4 Al + 3 O₂ → 2 Al₂O₃

Step 2: Calculate the theoretical yield of Al₂O₃

We first calculate the moles of aluminum (Al) used in the reaction.

  • Molar mass of aluminum (Al) = 27 g/mol

  • Moles of Al used = 27 g / 27 g/mol = 1 mol of Al

From the stoichiometry of the reaction, 4 moles of Al produce 2 moles of Al₂O₃. Therefore:

  • Moles of Al₂O₃ produced = (2 / 4) × 1 mol of Al = 0.5 mol of Al₂O₃

Now, calculate the mass of Al₂O₃ produced using its molar mass:

  • Molar mass of Al₂O₃ = (2 × 27) + (3 × 16) = 54 + 48 = 102 g/mol

  • Theoretical yield of Al₂O₃ = 0.5 mol × 102 g/mol = 51 g

Step 3: Calculate the percentage yield

The actual yield of Al₂O₃ is given as 4.95 g. The formula for percentage yield is:

Percentage Yield = (Actual Yield / Theoretical Yield) × 100

Substitute the values:

Percentage Yield = (4.95 g / 51 g) × 100 ≈ 9.7%

Final Answer:

The percentage yield of the reaction is approximately 9.7%.
