Hence it follows that nitrogen in $\ce{CH3CN}$ is more electronegative as compared to that in $\ce{NH_3}$, which makes $\ce{NH_3}$ more basic. (an electron is negatively charged a nucleus positively hence the closer the electron to the nucleus the more stable it is) e.g. False. The Acetonitrile molecule has a chemical formula of C 2 H 3 N. The carbon atom H3C is 2nd carbon while carbon attached to the nitrogen is the first carbon. sp3 sp2. The first carbon atom that has only two adjacent bonded atoms will have a linear geometry and so will have sp hybridization and the two p orbitals will form pi bonds with the adjacent nitrogen atom. So, yes, that is a polar bond. hybridization of n in ch3cn. Introduction; 2. Acetonitrile Answer: The nitrogen atom is part of a triple bond, so it needs two p orbitals (one p orbital for each of the two p bonds). The hybridization of the nitrogen atom in acetonitrile, a common organic solvent is: sp. It is produced mainly as a byproduct of acrylonitrile manufacture. Therefore, acetonitrile was chosen as the desorption solvent. In $\ce{NH_3}$ nitrogen is $\mathrm{sp^3}$ hybridized while in $\ce{CH3CN}$ nitrogen is $\mathrm{sp}$ hybridized. A. triethylamine.
