22. 1 How many spa-hybridized atoms are present in the compound shown bolow? @ o B} 3 . @4 H .. 5% D)1 G?

Why is the answer 4? I drew in the lone pairs on nitrogen because I thought you need to add them. In that case, you'd have 4 areas of electron density which make both nitrogens sp2 hybridized. Why is the correct answer 4 here instead of two?
