None of these structures are planar
Homework Answers
The lone pairs on the nitrogen atoms in trans-N2F2 are visible in the HOMO, and as they jot out in the plane of the molecule, that is a feature of sp2-hybridized orbitals! ... Those that are sp2-hybridized generally adopt a trigonal planar arrangement for both lone pairs and bonds to other atoms.
Each H2N−N subunit is pyramidal. The N−N single bond distance is 1.45 Å (145 pm), and the molecule adopts a gauche conformation. The rotational barrier is twice that of ethane. These structural properties resemble those of gaseous hydrogen peroxide, which adopts a "skewed" anticlinal conformation, and also experiences a strong rotational barrier.

Draw molecules that satisfy the following prompts i-iii. All molecules must have 8-10 Carbon atoms AND exactly 2 Heteroatoms (i.e. atoms that are not carbon or hydrogen atoms). You may not use the same molecule twice for any parts of this question. You do not need to look up solubility information, but the answers must be reasonable. Also, the structures must be reasonable (improper structures, e.g. carbon with 5 bonds, or oxygen with one bond and no charge, will not...
