※ 引述《ambivert (在我坟上起舞)》之铭言：
: : N2O4你可画出结构式，会发现无孤对电子，且4个O原子呈现对称，
: : 对N原子而言为3个住3个
: : 电偶极会抵消，故为非极性...
: : N2H4画完结构式发现有孤对电子存在，但对N原子呈现４个住３个形态，
: : 未住满故有极性..
: N2O4它的键结是有一个N和一个O间是双键 另一个是单键吗?
: 不好意思,因为如果是我就会画成N-N单键,其他对O都是N供电子给O....
一个是单键一个是双键(双键来自氧分子的lp 做为共振结构)

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?
