Bonding Structure

NO2 unstable------->會form N2O4  -->2個N都octet
H2O     O有2 lone pairs + 2 bond pairs  當佢既electrons pairs排列為tetrahedral shape果陣,repulsion就會係最 細   tetrahedral入面既四條邊就係4個electron pairs , 兩個bond pairs就會係V-shape--->H2O係V-shape
CO2      粒C正係得2 bond pairs , 2bond pairs 排列為linear shape時角度為180度,repulsion最細  所以佢係linear.

本人chem都唔係好好..解釋僅供參考..如有錯誤請指出...( 有唔明最好問老師~~~~~)

REQUIEM

CO2有兩對electron pairs
so 係linear

H2O有4對electron pairs
so 係tetrahedral
electron pairs 姐係no. of bond pair + no. of lone pair
如果淨係睇bond pair ge話..
h2o就係v-shape

我聽人講係咁嫁.. ...

點解CO2有兩對electron pair就係linear
4對electron pair就係tetrahedral既?

同埋 咩叫睇bond pair就係vshape?
