KCET 2017 Chemistry Solved Paper

For tetrahedral geometry:
No. of electron pair = 4
Bond pair = 4
Lone pair = 0For pyramidal geometry: No. of electron pair = 4
Bond pair = 3
Lone pair = 1For trigonal planar geometry: No. of electron pair = 3
Total bond pair = 3
Lone pair = 0For octahedral geometry: No. of electron pair = 6
Bond pair = 6
Lone pair = 0
