Can nitrogen form two double bonds?

Answer 1

Yes.

Nitrogen can form up to 4 bonds (which gives it 8 valence shell electrons). However, when it does form two double bonds, it will have a positive charge.

Remember that 2nd row elements cannot form more than 4 bonds or have more than 8 electrons (octet rule).

Answer 2

i think of this might nicely be a badly worded question. in case you had all those bonds, we might have six bonds to N. hence i think of what became into meant became into the two 2 sigmas and one pi, or 2 pi's which might contain 2 sigmas as portion of the pi as you suggested. In the two case, we might have 4 bonds to the nitrogen. Now which hybridization has 4 bonds? sp has 2 (combination one s and one p), sp2 has 3, sp3 has 4, BINGO, shall we bypass on nonetheless dsp3 has 5 and d2sp3 has 6.

Answer 3

No . Yhe valence of nitrogen is three. So not possible
