Part 1: Identification & True/False Flashcards
Identify if the statement is TRUE OR FALSE.
It refers to the geometric twist in any non-linear molecular system in a degenerate electronic state to form a system of lower symmetry and lower energy thereby removing degeneracy
Jahn-Teller effect
It is the type of isomerism that results from the interchange of an anionic ligand within the first coordination sphere with an anion outside the coordination sphere
Ionization isomerism
It is the difference of energy between the two sets orbitals, one with lower energy and the other with higher energy, when ligand approaches a transition metal ion.
crystal field splitting energy
It is a two-stage medical treatment that combines light energy with a drug (photosensitizer) designed to destroy cancerous and precancerous cells
Photodynamic therapy (PDT)
It is a platinum-based chemotherapy drug used to treat various cancers by inhibiting DNA synthesis and creating crosslinks between DNA strands and can also impact other cellular processes, including antioxidant defense, calcium homeostasis, and inflammation.

TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
The compounds [Pt(NH3)2Cl2] can exhibit cis-trans isomerism
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
The complexes [Co(NH3)4Cl2]Cl and [Co(NH3)4Cl]Cl2 are examples of coordination isomers
FALSE.
The complexes are examples of ionization isomers.
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Optical isomerism can occur in square planar complexes
FALSE.
Optical isomerism typically occurs in octahedral complexes with non-identical ligands. Square planar complexes often lack the necessary chiral centers for optical activity.
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
In valence bond theory, a sigma bond is formed by the side to side overlap of atomic orbitals.
FALSE.
Pi bond
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
According to valence bond theory, the concept of hybridization explains the mixing of atomic orbitals to form new hybrid orbitals.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
In molecular orbital theory, a sigma bond is formed by the head-on overlap of atomic orbitals.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
According to molecular orbital theory electrons in bonding orbitals contribute to the stability of a molecule, while electrons in antibonding orbitals destabilize the molecule.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
In crystal field theory, ligands cause splitting of the d orbitals in a metal ion, leading to the formation of molecular orbitals.
FALSE.
In crystal field theory, ligands cause splitting of the d orbitals in a metal ion, leading to the formation of d-orbital energy levels
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Crystal field theory predicts that in a square planar complex, the d orbitals of a metal ion are split into two sets: three higher energy orbitals and two lower-energy orbitals.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
In ligand field theory, the splitting of d orbitals in a metal ion is influenced by the geometry of the coordination complex and the nature of the ligands.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Inorganic catalysts accelerate chemical reactions by undergoing permanent changes in their molecular structure.
FALSE
Inorganic catalysts accelerate chemical reactions by undergoing temporary changes in their molecular structure. They return to their original state after the reaction is complete.
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Hemoglobin is an iron-containing coordination complex responsible for oxygen transport in the blood.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.

TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Chemical sensors can detect specific chemical compounds in a sample through a chemical reaction that produces a measurable signal.
TRUE
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
A photodiode is a sensor that converts mechanical energy into electrical energy.
FALSE. It coverts light energy
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Cisplatin is effective against all types of cancer.
FALSE. Cisplatin is effective against some types of cancer, particularly testicular and ovarian cancers. It is not effective against all types of cancer.
STATE IF THE STATEMENT IS TRUE or FALSE if FALSE give the correct answer.
Cisplatin is classified as an alkylating-like agent.
