NAT MCQs

Triple bonds have higher bond order than single or double bonds.
They are usually shorter and stronger.

Rectangle area is length multiplied by width.
Thus, 12 × 7 = 84 m².

No single resonance structure fully represents the electron distribution.
The real structure is a resonance hybrid.

Square area is side squared.
Thus, 9² = 81 cm².

Formal charge helps compare possible Lewis structures.
Preferred structures often minimize charge separation.

The side length is √144 = 12 cm.
The perimeter is 4 × 12 = 48 cm.

Electron groups arrange to minimize repulsion.
Lone pairs and bonding regions determine molecular geometry.

Triangle area is one-half × base × height.
Thus, 1/2 × 10 × 6 = 30 cm².

Two electron groups arrange 180 degrees apart.
This minimizes repulsion.

Parallelogram area is base times perpendicular height.
Thus, 15 × 8 = 120 cm².

Three electron groups arrange about 120 degrees apart.
They lie in one plane.

Four electron groups point toward tetrahedral corners.
The ideal bond angle is about 109.5 degrees.
