(a)
To determine: The plane of symmetry if the molecule has an internal plane of symmetry and if the structure is chiral on absence of plane of symmetry.
Interpretation: The validation of the statement that the given molecule contains a plane of symmetry is to be stated and on absence of plane of symmetry, the chirality of the molecule is to be detected.
Concept introduction: A carbon which has all the four different atoms or group of atoms show tetrahedral geometry is referred to as the chiral carbon. The mirror image of an object that contains chiral carbon has non-super imposable mirror image. The two different forms in which a single chiral carbon can exist is referred to as enantiomers. The number of enantiomers of a molecule depends on the number of chiral centres.

- Identify the figure they are with mirror plane or without mirror plane. Figure 1 A- B- C- How many chiral carbons are there in the structure? Figure 2arrow_forwardFor each of the following molecules, assign whether the molecule is chiral or achiralarrow_forwardFor the compounds shown, use the R/S configuration given in the compound name to finish drawing the structure by changing bonds to the the appropriate wedge‑and‑dash bonds. For each compound, change two of the in‑plane bonds to a wedge and a dashed bond. You can select the chiral bond and click on top of an in‑plane bond to quickly modify it.arrow_forward
- How many chiral centers are in each of the molecules and how to find them?arrow_forwardWhich of the following statements are true? Explain.I. If a molecule has a plane of symmetry it is achiral.II. If a molecule has a center of symmetry it is achiral.III. If a molecule has one stereogenic center it is chiral.arrow_forwardSketch this molecule and then draw a circle around all the chiral carbons that you can find. 1. Classify the type of isomerism (if any) shown by the compounds below.arrow_forward
- The best definition of a chiral molecule is a molecule that has NO plane of symmetry. Sometimes, chiral molecules have no chiral centers. Alternatively, some molecules with chiral centers are not chiral. This molecule has no plane of symmetry and is chiral. Chiral molecules will interact with plane polarized light. Determine if this molecule is optically active.arrow_forwardWhat type of stereochemistry, S or R, does the chiral center in this molecule have?arrow_forwardA molecule that possesses an internal plane of symmetry can never be chiral.
