動詞可能形 + 〜ものなら: 〜ことが可能なら (実現が難しいことについて言うことが多い) "If only I could/may...,"
〜う/ようものなら: もし〜ようなことをしたら...(大変なことになる) Once if (one) happen to ... , then (bad consequence)."
誠
Used when one wishes to do something difficult. Usually used together with the potential form.

"if" does not quite get you there. For example, "If I come home late, he won't let me in" should perhaps be "Would I come home late, he won't let me in the house." ものなら is not iffy.

ex #3724 has nothing to do with this grammar point. 甘いもの (= sweets) just happens to be suffixed with なら (group 3)

Shouldn't ex #3722 be better translated as: "Whatever you pick for me is fine"?

-ようものなら is quite iffy. it denotes a hypothetical condition. [if i came home late, he wouldn't let me in]

ex #3719 is 〜もの(thing) + ならば, and therefore does not belong to the usage of 〜ものなら . From ex#3719 to ex#3724, it doesn't give the meaning or correct usage of 〜ものなら, therefore treat it as 〜もの + なら。 〜ものなら always follow the 可能形 potential form. and used to indicate something difficult to realize, or some ideal thinking of the writer,e.g. : "If only i was still a child, ...."
誠
ex #3228 belongs to 〜う/ようものなら: My father is very strict. Once if I happen to come home late, my dad won't let me in.
誠
〜ものなら: "If only I could/may.....", "If only it was possible to ....", "If only it was possible that..."

Added ex #5896 for 〜ようものなら

Do we need both #3717 and #3718? I don't see why the same sentence is listed twice because of one kanji...
