Q4.Methyl isocyanate, CH3NCO, is a toxic liquid which is used in the manufacture of somepesticides.In the methyl isocyanate molecule, the sequence of atoms is H3C—N C O.What is the approximate angle between the bonds formed by the N atom?A104°B109°C120°D180°
MS says it's C, however i don't quite understand.
I figured that Nitrogen would have 2 lone pairs left over, therefore it will have a tetrahedral shape (repulsion between the 2 C's and the 2 lone pairs), resulting in 104 degrees.
