推 jimmy30637:請問BOND ORDER是? 04/11 10:10
→ luckywu7557:鍵序(數) 04/11 13:11
※ 引述《jimmy30637 (昝肥)》之銘言：
: 1.Predict and explain which substance in each of the following pairs would have
: the greater intermolecular forces.
: a. CO2 or OCS b. CH3CH3 or H2CO
: 請問要怎麼比分子間作用力(凡德瓦力)
有氫鍵最大 在來看分子量 分子像相近者看極性
所以OCS > CO2 H2CO3(有3吧?)>CH3CH3
: 2.Determine (1) the electron configuration, (2) bond order, and (3) magnetism
: 2- 2- -
: for S2, N2, and CN.
: 這題請問是要先把路易士結構畫出來吧 請問(3)要怎麼判斷磁性?
2 ＊2 2 4 ＊4
用MO S2^2-:σ3S σ3S σ3P π3P π3P diamegnetic, bond order=1
2- 2 ＊2 4 2 *2
N2 :σ2S σ2S π2P σ2P π2P paramegnetic, bond order=2
- 2 *2 4 2
CN : σ2S σ2S π2P σ2P diamegnetic bond order=3
: 3.Write Lewis structures that obey the octet rule for the following species.
: Assign the formal charge for each central atom.
: 3-
: a. SO2Cl2 b. NO4
用BBS好難畫 大概是把所有情形畫出來
以上答案還要強者鑑定
