Which atomic orbitals are involved in bonding and which as lone pair orbitals for N2H2?
H−N¨=N¨−H

bonding: sp2 on both H and N; lone pair: p on N
bonding: s on H, sp2 and p on N; lone pair: sp2 on N
bonding: s on H, p on N; lone pair: sp2 on N
bonding: s on H, sp2 on N; lone pair: p on N

	bonding: sp2 on both H and N; lone pair: p on N
	bonding: s on H, sp2 and p on N; lone pair: sp2 on N
	bonding: s on H, p on N; lone pair: sp2 on N
	bonding: s on H, sp2 on N; lone pair: p on N
