20) Explain SP2 hybridisation of BCL3paantinho tynes of Hudropen b |
|
Answer» AB3 A is a central atom and B are the atoms bonded to the central atom.A species of this type have three bonding electron pair and no lone pair (bp=3,lp=0).These bonding electron pair occupy their position as far as possible so that the electrostatuc repulsion between them is minimum.This is most probable if the bond angle between them is 120•.Thus such species have trigonal planar or equvalent truangle,geometry. Examples BCl3,BF3,BH3,So3 ,etc. |
