Case Study Questions for Class 11 Chemistry Chapter 2 Structure of Atom

Case Study/Passage Based Questions:

Question 1:

Electron moves around the nucleus in circular orbitals in fixed energy paths. As far as electron moves in these orbits neither energy is absorbed nor liberated. But when electron move from lower energy level to higher energy level energy is absorbed while when it comes back from higher energy level to lower energy level energy is liberated in the form of photon & a spectral line is formed. Corresponding to different possible transitions different lines are formed which form the particular serieses viz. lyman, balmer, paschen, bracket, pfund, Humphery etc. Suppose e– in hydrogen atom is present in 10th excited state, then answer the following questions based on paragraph:    

(i) If electron present in 10th excited state liberate one visible quanta then next quanta liberated will correspond to following transition –              
(A) 10 → 2  
(B) 11 → 2 
(C) 11 → 1  
(D) 2 → 1            

(ii) Total number of spectral lines which can be obtained during the transition to ground level –
(A) 45
(B) 55
(C) 66 
(D) 36      

(iii) Minimum value of wavelength that can be obtained during the transition – (Where R is Rydberg constant.)
(A) 121/120R 
(B) 11/10R 
(C) 100/99R 
(D) 10/9R
