Decreases
Oxoacid with an OH group bonded to an element that is not bound to other oxygens
HOY acids
Oxoacid where an OH group is bonded to an element that is bonded to other oxygens
HYO acids
In HOY acids, acid strength ___________ as the electronegativity of y increases
Increases
In HYO acids, acid strength ____________ as more Oxygens are added to the central Y
Increases
Weak organic acids
Carboxylic acids
In carboxylic acids, the more electronegative the elements that make ‘R’ the ____________ the acid
stronger
