Determining the hemisphere is easy: latitude zones a, C, d, e, F, g, h, J, K, l, and m are in the Southern hemisphere, and the rest are in the Northern hemisphere. 这种确定非常简单：纬度区a、C、D、E、F、G、H、J、K、L和m位于南半球，而其余区位于北半球。 - 2
So it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there. 这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话，这样我们就有氢与碳之间的单键和碳与氮之间三键，然后还有一对孤对电子在氮这里。 - 3
So, why don't you go ahead and tell me, keeping that in mind, which atom in terms of h c or n would you expect to be in the center of hydrogen cyanide? 那么，请大家来告诉我，并且记住它，你认为氢，碳和氮中哪个原子,应该在氰化氢的中间呢？
