CO2 here has the charge asymmetry locked up, but because the molecule is linear, in a straight line, it's a kind of symmetrical asymmetry.

CO2 在这里锁定了电荷不对称性，但是因为分子是线性的， 在一条直线上， 这是一种对称的不对称性。

If you were paying attention, you learned that a molecule needs to have both charge asymmetry and geometric asymmetry to be non-polar, that charge asymmetry is caused by a difference in electronegativities, and that I am totally team polar.

如果你注意的话，你就会知道一个分子需要同时具有电荷不对称性和几何不对称性才能成为非极性的， 电荷不对称是由电负性的差异引起的， 而我完全是团队极性的。
