我老師好熱心教好多out sy 野-,-
係H-Cl入面
H係+ve, Cl係-ve
咁H同另一個HCl入面0既Cl就有一個attraction
呢個係dipole-dipole attraction
H 係slightly positive, Cl 係slightly negative <= due to EN difference
所以個bonding e- cloud 係partly shift towards the internuclear axis of Cl => permanent dipole is formed
同adjacent molecules , 有相反charge 的attraction 係叫permanent-dipole permanent-dipole interaction/ attraction
佢d molecules 比較自然會oriented 去一個form in which repulsion is minimized + attraction is maxmized ..
舊out-c 野, 都幾好, 我個人認為, 有d 招式係幾好用for CE |
