Prof: Speak up a little bit.

稍微大声点
Student: It's the same molecule but a different structure.

同样地分子但结构不同
Prof: The same molecule but a different structure.

相同分子不同结构
But isn't structure a molecule?

但结构不就代表分子吗
Student: But with that I guess --

这么说的话
Prof: You know like, let me just interject a minute here.

让我插进来讲一分钟
Like, one of the problems is HCNO in any order.

HCNO的任意排序是问题之一
So there would be different molecules with C in the middle,

当把C或O或N放在中间时
N in the middle, O in the middle.

会得到不同的分子
Is that what you mean?

你是这个意思吗
Student: No. I mean like it's -- if you have a double or a triple bond,

不我的意思是分子内的单键或三键
it's in a different location,it's around the central atom.

可能处在中心原子的两侧
