Chemical Bonding

Question 1

Formula

What is the formula for calculation of Lone pair on molecules

Answer 1

Group number of central atom- valency of side atoms

Question 2

Formula for calculation of Lone pair on ions

Answer 2

L.P =G no of central atom - valency of atoms

SO4^2-
=S- 40
=5 + 2-40
= 6+2=4(2)
= 0 es No lone pair

Question 3

Answer 3

2- sp- Linear
3- sp2- trigonal
4- sp3- tetrahedral
5- sp3d- trigonal bipyramidal
6- sp3d2- octahedral

Question 4

Trick to calculate hybridization of Central atom

Answer 4

H= Lone pairs+ number of surrounding atoms
