Quantum Mechanics In Chemistry

Question 1

Equation to find bond order

Answer 1

Bond order = (no. of bonding electrons - no. of antibonding electrons) / 2

Question 2

Diamagnetic and paramagnetic

Answer 2

Diamagnetic - no unpaired spins

Paramagnetic - some unpaired spins

Question 3

Coordinate covalent or dative bond

Answer 3

When one atom “provides” both electrons.

E.g. NH3 + H+ –> NH4+ (since H+ has no electrons, both electrons in the new bond came from N)
