please answer all True or False questions

11. The greater the bond order, the shorter and stronger the bond 12. bonding orbitals have even (gerade) parity 13. antibonding orbitals have odd (ungerade) parity 14. If p orbital of one atom with axis perpendicular to the internuclear axis is brought up to an s orbital of another atom, no molecular bonding can occur. 15. Two p orbitals of two different atoms with axes parallel to the internuclear axis are brought together: bonding can occur 16. The orbitals ( orbitals) formed by p orbitals of two different atoms perpendicular to their internuclear axis can form (bonding) and (antibonding) orbitals 17. The orbitals are doubly degenerate 18. The bond order N2 molecule is 3 19. A molecular orbital for heteronuclear diatomics can be represented as a superposition of atomic orbitals with different weights cA and cB:=cAA+cBB 20. An angular triatomic molecule with a characteristic bond angle (=180) is not necessarily planar 11.
