Q32.The plots of radial distribution functions for various orbitals of hydrogen atom against ' r′ are given below. The correct plot for 3s orbital is : (1) (2) (3) (4)
What This Question Tests
This question tests the ability to determine the percentage of oxygen in an organic compound by calculating the mass of carbon and hydrogen from the combustion products and then finding the remaining mass as oxygen.
Concepts Tested
Formulas Used
Mass of element in compound = (Mass of compound / Molar mass of compound) * Molar mass of element
Percentage = (Mass of element / Total mass of compound) * 100
