Homework Answers
Acidity means removal of acidic proton & breaking of bond of acidic proton and other atom/group and bonded electrons go with other atom/group.
Let A-H is a molecule. Thus acidity of A-H directly proportional to electronegativity of A and ease of bond breaking.
Answer(5)
In question there is positive charges on N ,C and O.
We already know that in these three electronegativity order is
C<N<O .
Positive charge on charge each cause more increases the electronegativity.
Since C is least electroengative hence C-H bond breaks very slowly . Hence shows weakest acidity. ( kindly see the image)
Answer(6)
Most acidic proton is that which is removed fastest from the site. In option (a) both N &O have positive charge but oxygen is more electronegative. Hence proton of side of O is more acidic.
In option (b) both side oxygen but that side having positive charged oxygen is more electronegative. Thus proton of positive oxygen side is more acidic. (Please see the image)
