If A is more electronegative than B for H—A and H—B:



~ 16 ~



H^δ+---- A^δ− and H^δ+ ---- B^δ−



1) Atom A is more negative than atom B ⇒ the proton of H—A is more positive



than that of H—B ⇒ the proton of H—A will be held less strongly ⇒ the



proton of H—A will separate and be transferred to a base more readily.



 

this is from an organic e book......i did'nt get  this part...."the proton of H—A will be held less strongly"....

plzzz explain..
