trigonal

基本解釋

So it's trigonal pyramidal.
所以它是三角形金字塔。
The shape is actually trigonal pyramidal.
它的形狀是三角金字塔形。
So it's trigonal because we have these three atoms that are bound to the central atom here, and if you picture it, it's actually shaped like a pyramid.
這裡三角形是因爲(wèi),我們有3個(gè)原子核中心原子成鍵，如果你畫它，它就是金字塔形的。

So it's trigonal because we have these three atoms that are bound to the central atom here, and if you picture it, it's actually shaped like a pyramid.
這裡三角形是因爲(wèi),我們有3個(gè)原子核中心原子成鍵，如果你畫它，它就是金字塔形的。

So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.
讓電子勁量遠(yuǎn)離的時(shí)候，不用考慮它,這個(gè)例子是平麪三角形，你可以看到，衹有3個(gè)電子可以成鍵。

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.
如果我們考慮碳原子的形狀，它是平麪三角形，鍵角是，因爲(wèi)我們有這三個(gè)襍化軌道。
