※ 引述《ambivert (在我墳上起舞)》之銘言：
: : N2O4你可畫出結構式，會發現無孤對電子，且4個O原子呈現對稱，
: : 對N原子而言為3個住3個
: : 電偶極會抵消，故為非極性...
: : N2H4畫完結構式發現有孤對電子存在，但對N原子呈現４個住３個形態，
: : 未住滿故有極性..
: N2O4它的鍵結是有一個N和一個O間是雙鍵 另一個是單鍵嗎?
: 不好意思,因為如果是我就會畫成N-N單鍵,其他對O都是N供電子給O....
一個是單鍵一個是雙鍵(雙鍵來自氧分子的lp 做為共振結構)

I was so simple yesterday. It let me remember the time I was young,
laugh so naturally and cry so causually.
I changed myself and thought could leave no marks. Nobody felt I was
in pain. Nobody could see I was bridling. I didn't look like myself already.
I wanted to give you all the happiness in my life whatever I could.
Why did you keep pretending your hardness?
