Question

Give the decreasing order of the stability of the following or increasing order of heat of combustion
I) 
II) 
III) 

  1. open parentheses I close parentheses greater than open parentheses I I close parentheses greater than left parenthesis I I I right parenthesis    
  2. open parentheses I I I close parentheses greater than open parentheses I I close parentheses greater than left parenthesis I right parenthesis    
  3. (II)>(III)>(I)    
  4. (I)>(III)>(II)    

The correct answer is: open parentheses I close parentheses greater than open parentheses I I close parentheses greater than left parenthesis I I I right parenthesis


    Lower is the heat of combustion, more stable is the compound. Lesser is the angle strain, more stable is the compound. So, the ANSwer is (a)left parenthesis I greater than I I greater than I I I right parenthesis
