what is hybrid state of central atom in the following
NO-3, BF-4,PF5,IF3 AND CO2...??
Answers
Explanation:
NO3- BF4- PF5 IF5 CO2. N in NO3- is sp2hybridised B in BF4- is sp3hybridised P in PF5 is sp3d hybridized C in CO2 is sp hybridized.
We have to find out hybridisation of central atom in the following..
NO₃¯ , BF₄¯ , PF₅ , IF₃ and CO₂
solution : using VSEPR (valence shell elecron pairs repulsion) theory,
for NO₃¯,
no of bond pairs = 3
no of lone pairs = (3 × 6 + 5 + 1 - 3 × 8)/2
= (18 + 6 - 24)/2 = 0
so hybridisation must be sp²
for BF₄¯
no of bond pairs = 4
no of lone pairs = (4 × 7 + 3 + 1 - 4 × 8)/2 = 0
so hybridisation is sp³
for PF₅
no of bond pairs = 5
no of lone pairs = (5 × 7 + 5 - 5 × 8)/2 = 0
so hybridisation is sp³d
for IF₃
no of bond pairs = 3
no of lone pairs = (7 + 3 × 7 - 3 × 8)/2 = 2
so hybridisation is sp³d
for CO₂
no of bond pairs = 2
no of lone pairs = (6 × 2 + 4 - 2 × 8)/2 = 0
so hybridisation is sp
