expanded octet造句

例句与造句

1. You are correct-sulfur contains an expanded octet-two double bonds, two single bonds, for a grand total of 12 valence electrons.
2. Single bonds can also be moved in the same way to create resonance structures for hypervalent molecules such as sulfur hexafluoride, which is the correct description according to quantum chemical calculations instead of the common expanded octet model.
3. In the late 1920s and 1930s, Sugden argued for the existence of a two-center one-electron ( 2c-1e ) bond and thus rationalized bonding in hypervalent molecules without the need for expanded octets or ionic bond character; this was poorly accepted at the time.
4. However, when you get down to the " nitty gritty ", expanded octet molecules are better explained by molecular orbital theory, in that their bonding angles and bonding distances are better modeled by that theory than hybridization theory; hybridizing d-orbitals with s and p from the same n-level don't produce realistic results given the large energy gaps involved .-- 32 " "'13 : 00, 23 May 2011 ( UTC)
