Question

Use Examples 4.16 to determine the  hybridization for each central atom ( respectively C, C, O, N)in the following molecule:

CH₃COONH₂

Group of answer choices

sp3, sp2, sp2, sp3

sp3, sp2, sp, sp2

sp3, sp2, sp , sp3d

sp3, sp2, sp3, sp3

Answer 1

Answer:-

Step 1:-

Hybridisation index (I) = GA + 1/2 (VE - V - C)

Where, GA = Number of groups or atoms attached to the central atom

VE = Number of valance electrons present in the central atom

V = Valance of the central atom

C = Charge (if species is ionic)

Step 2:-

After knowing the value of I, the hybrid state is predicted as:

Value of I	2	3	4	5	6	7
Hybrid state of central atom	sp	sp2	sp3	sp3d	sp​​​​​​​3​​​​​​​d2	sp3d3

---------------------------------------------

​​​​​​​

i) Taking *C atom as central atom:

I = 4 + 1/2 × (4 - 4 - 0) = 4 = sp³

---------------------------------------------

ii) Taking **C atom as central atom:

I = 3 + 1/2 × (4 - 4 - 0) = 3 = sp²

---------------------------------------------

iii) Taking *O atom as central atom:

I = 2 + 1/2 × (6 - 2) = 4 = sp³

---------------------------------------------

iv) Taking N atom as central atom:

I = 3 + 1/2 × (5 - 3) = 4 = sp³

---------------------------------------------

Hence , correct answer is option 4) - sp³ , sp² , sp³ , and sp³ .
