搭單問 allotropes def 使唔使背
同埋hydrogen bond def 寫
weak electrostatic force of attractions between a hydrogen atom of a highly polarized bond of an molecule and a lone pair electrons of a highly electronegative atom of another atom 得唔得

Hydrogen bond: electrostatic attraction between the partial positively charged H that bonded with highly electronegative atom (N/O/F) with lone pair electrons on the highly electronegative atom (N/O/F) of another molecule.

呢個如果同學仔覺得難記
我建議畫個圖 例如兩個H-F之間個hydrogen bond
之後自己用英文描述所有你見到嘅嘢
