Question

Determine the hybridization around the indicated atoms in the following molecule: CH3 =N b

Answer 1

Method (1)

Note:

Carbon atoms with ..

(1) 4 sigma bond = sp^{​​​​​3} hybridization

(2) 3 sigma + 1 pi bond = sp^{​​​​​2} hybridization

(3) 2 sigma + 2 pi bond = sp hybridization

Nitrogen atoms with...

(1) 3 sigma bond + 1 lone pair of electrons = sp^​​​3 hybridization

(2) 2 sigma bond + 1 lone pair + 1 pi bond = sp^{​​​​​2} hybridization

(3) 1sigma bond + 1 lone pair + 2 0i bond = sp hybridization.

CH₃ Sigmabond pi bend Ň Sigmabond sigmabond signa bon bond * @ Carbon atom contained 3 sigma + 1 pi bond = sp2 hybridization * 6 Nitrogen atom contanined 2 sigma bond+ 1 pibond + 1 lonepaist of election = sp² hybridization

Method (2)

In hybridization, only the lone pair of electron, and sigma bonds are used.

* C = 15225²26² * Curbon in golound s late 1.1] [/ 11 25 C= * Mixing of osibilal C It T 1 1 1 1 1 1 1 11 hybridization= sp? *O_N = 18? 28%2p3 Nitrogen in ground stele ON= 1 oltin Mixing ofoobital cllz hybridization=sp2

So,

a = sp^{​​​​​2}

b =sp^{​​​​​2}
