  1. 2R    
  2. R left parenthesis 1 plus square root of 2 right parenthesis    
  3. R square root of 2    
  4. R left parenthesis square root of 2 minus 1 right parenthesis    

The correct answer is: R left parenthesis 1 plus square root of 2 right parenthesis


    R subscript text net end text end subscript equals R plus square root of R to the power of 2 end exponent plus R to the power of 2 end exponent end root equals R plus square root of 2 R equals R left parenthesis square root of 2 plus 1

    Tautomerism is the phenomenon in which two structural isomers differing in the relative positions of their atoms are spontaneously interconvertable and can exist in dynamic equilibrium. The two forms in tautomeric equilibrium are called tautomers of each other. The interconvertibility of tautomers is a chemical reaction which involves making and braking of bonds. Tautomers are true isomers, and either of the individual tautomeric forms may be isolated

    In the keto-enoltautomerism of dicarbonyl compounds the enol form is preferred in contrast to the keto form, this is due to
