So we end up with a formal charge on carbon of negative 1.
因此最终我们得到碳的形式电荷量是负一。
And what you find out if you do these calculations, is that you have a negative 1 for your formal charge on nitrogen, you have a negative 2 for your formal charge on carbon, and you have a positive 2 for your formal charge on sulfur.
而如果你做了这些计算会发现,氮的形式电荷量为负一,碳的形式电荷量为负二,而硫的形式电荷量为正二。
