We have two lone pairs, so if we thought about what the bonds were everywhere, 5° it would be 109 . 5, but it's bent because we're only looking at the bonds, we're not counting the Lewis structures in naming our geometry, but they do affect the angles.
我们有两个孤对,所以如果我们考虑它会成怎样的键时,应该成109。,但它是折线型,因为我们只考虑成键,在几何形状里不考虑Lewis结构,但它会影响角度。
