HA binary acids?

Question

which of the following statements are true (more than one is correct)?


a) For binary acids HA in the same row of the periodic table, the greater the electronegativity of A
the stronger the acid HA

b) For binary acids HA in the same column of the periodic table, the stronger the H-A bond
the stronger the acid HA

c) HBr is a stronger acid than HCl

d) H2SO3 is a weaker acid than H2SO4

e) HClO is a stronger acid than HBrO

f) For carboxylic acids : the greater the electronegativities of the atoms in the group bonded to the carboxyl group,
the stronger the acid

The following choices are incorrect: acdf, acd, ade, and acde

Answer 1

I think I've answered this before...

The more electronegative the atom that is connected to H (or near the atom that is connected to H) the more stable the conjugate base will be, (the more reluctant to take a H+, thus weaker base) and the stronger the conjugate acid.

a) is true

b) is false; astrong H-A bond will break with more difficulty thus the acid is weaker

c) is false because Br is less electronegative than Cl

d)True because you have more electronegative O (4 instead of 3) which stabilize the anion better (you also have more resonance structures)

e) is true

f) is true

So you have adef

Answer 2

a. authentic b. No - the stronger the bond the tougher this is to dissociate. potential of an acid relies upon on how plenty it dissociates so weaker bonds are much less confusing to "destroy" or dissociate. c. fake - in dilute aqueous thoughts, HCl, HBr and hi are thoroughly ionized and all coach the comparable obvious acid potential. Water is satisfactorily consumer-friendly that it would not distinguish between the acid strengths and subsequently this is spoke of as leveling agent for those acids. d. authentic - acid potential in maximum ternary acids containing the comparable substantial atom (S for that reason) improve with increasing oxidation state of the substantial element and with increasing numbers of oxygen atoms. e. authentic - for many ternary aids containing diverse components in the comparable oxidation state from the comparable team in the periodic tale, acid strengths improve with increasing electronegativity of the substantial atom.
