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..

could i have the link to download the e book which u r reading...maybee if i read the book, i can understand ur quesion thoroughly.

ok...now A is more electronegative than B

with increasing electronegativity, the H-A bond bcums more polar.

so,the proton of H—A will be held less strongly  or u can say the release of proton is easily facilitated.

yes, in the book

its

HI>HBr>HCl>HF

bt here , even the size plays a role doesnt it??

i mean is stable coz of its size....so removal of  H+ will be facilitated easily

well

u see

A is more electronegative than B

so the bond between H-A will be weaker than H-B

so H-A will react with bases readily than H-B
