Interpretation:
The molecular model that doesn’t have a tetrahedral central atom in the given molecular models is to be identified.
Concept introduction:
Molecular shape can be predicted from the Lewis structure by using the valence-shell Electron-pair repulsion (VSEPR) model.
-Count the number of valence electron pairs (bond pairs and lone pairs).
-Assume that the valence electron pairs form a structure that allows them to be as far away from each other as possible.
-If there are only two bond pair electrons, the molecule is linear.
-If there are three bond pair electrons, the molecule is shaped like a trigonal planar.
-If there are four bond pair electrons, the molecule is shaped as a regular tetrahedral.
- Repulsion between lone pair-bond pair of electrons effect the geometry of molecules.
Bond angle is the angle between two bonds of a molecule and it is determined based on the geometry.

Stereoisomers are always nonsuperimposable mirror images of each other. d. Stereoisomers always possess handedness.arrow_forwardWhat is the total number of hydrogen bonds formed from the complex of the given structure?arrow_forwardA principal shell with a value of n=3 would contain s,p,d, and f orbitals true or falsearrow_forward
- A compound with empirical formula C2H5O was found in a separate experiment to have a molar mass of approximately 90 g. What is the molecular formula of the compound?arrow_forwardIf one compound has the formula C5H10 and another has the formula C4H10, are the two compounds isomers? Explain.arrow_forwardAnother major use of bismuth has been as an ingredient in low-melting metal alloys, such as those used in firesprinkler systems and in typesetting. The element itself is a brittle white crystalline solid. How do these characteristicsfit with the fact that bismuth is in the same periodic group with such nonmetallic elements as nitrogenand phosphorus?arrow_forward
- How many total isomers are possible in the picture?arrow_forwardGlucose-1-phosphate has a ΔG°′ value of −20.9 kJ/mol, whereas that for glucose-6-phosphate is −12.5 kJ/mol. After reviewing the molecular structures of these compounds, explain why there is such a difference in these values.arrow_forwardUse Frost Circles to complete the molecular orbital diagram for cyclooctatetrane. Label the bonding, non bonding, and anti bonding MO’s. If the molecule is planar, would it be aromatic, antiaromatic, or nonaromatic? If the molecule is nonplanar, would it be aromatic, antiaromatic, or nonaromatic?arrow_forward
- V and K are constants that are > 0, explain why the units of K and V are μm and μm/s respectively?arrow_forwardIt is speculated that, in 1954, the scientist Allan Turing (who was instrumental in decoding the German Enigma code during the Second World War) ate an apple, which had been injected with a solution of cyanide, to commit suicide. How does cyanide poisoning work on a molecular level, and why can this type of toxic effect not be prevented as in the case of methanol poisoning?arrow_forwardWrite the condensed structure of the following:arrow_forward
