Q52.The value of Rydberg constant (RH) is 2.18 × 10−18 J. The velocity of electron having mass 9.1 × 10−31 kg in Bohr's first orbit of hydrogen atom = _______ ×105 ms−1 (nearest integer).
What This Question Tests
This numerical problem involves calculating the percentage yield for the bromination of aniline. It requires knowledge that aniline undergoes tribromination due to the strong activating effect of the -NH2 group, calculating theoretical yield, and then applying the percentage yield formula.
Concepts Tested
Formulas Used
Moles = Mass / Molar mass
Percentage yield = (Actual yield / Theoretical yield) * 100
