之前我回答其中一題的確有錯..
若這題也有錯的..請指出..因為不想誤人子弟....也讓我知道自己的錯處..
thanks..老爺子..

THANKS 老爺子

I appreciate the effort that you guys put in. Honesty, I am a dummy of chemistry that's y u can see I make several post on here. On the giving points stuff, I wish I can give points to everyone that help me to be succeed.

本想回答，但翻查最近三次回答同一發問者的紀錄，每次答得都很用心回答，並加以解釋，可惜前兩次發問者都選了一個有錯而沒有解釋的001答案。為了保持良好紀錄，還是不回答為妙。

1.
The answer should be "T-shaped, linear, trigonal bipyramidal".
