MCOCD #4

The exact spatial arrangement of atoms or groups in a chiral molecule around a single chiral atom, designated by (R) or (S).

• Mobile Phase

• Absolute Conformation

• Spin Quantum Number (m_s )

• Stationary Phase

Nonsuperimposable stereoisomers that are mirror images of each other. Enantiomers differ in configuration at every chiral center but share the same physical and chemical properties in a nonstereospecific (achiral) environment. Their optical activities are exactly the opposite of each other.

• Spin Quantum Number (m_s )

• Enantiomers

• Diastereomers

• Mobile Phase

Stereoisomers that are not mirror images of each other Diastereomers differ in their configurations at least one chiral center and share the same configuration at least one chiral center. They differ in physical and chemical properties.

• Relative Configuration

• Stationary Phase

• Equatorial

• Diastereomers

Energy created in a cyclic molecule by angle strain, torsional strain, and nonbonded strain; determines whether a ring is stable enough to stay intact.

• Ring Strain

• Gabriel (Malonic-Ester) Synthesis

• Newman Projection

• Nucleophile

In an IR spectrum, the region of 1400 to 400 cm^-1 where more complex vibration patterns, caused by the motion of the molecule as whole, can be seen; it is characteristic of each individual molecule.

• Electron-Donating

• Achiral

• Fingerprint Region

• Enol

Laboratory technique that relies on measurement of the energy differences between the possible states of a molecular system by determining the frequencies of electromagnetic radiation (light) absorbed by the molecules or their response to a magnetic field.

• Spectroscopy

• Newman Projection

• Phosphodiester Bond

• Mobile Phase

The resonance form of a carbonyl that has a carbon-carbon double bond (ene) and alcohol (-ol)

• Phosphodiester Bond

• Oxidation State

• Mobile Phase

• Enol

A method of visualizing a compound in which the line of sight is down a carbon-carbon bond axis.

• Optical Isomers

• Achiral

• Newman Projection

• Carbonyl Group

An alcohol with an aromatic ring; has slightly more acidic hydroxyl hydrogens than other alcohols.

• Nucleophile

• Phenol

• Optical Isomers

• Phosphodiester Bond

A type of bond that links the sugar moieties of adjacent nucleotides in DNA.

• Phosphodiester Bond

• Pi (π) Bond

• Oxidation State

• Carbonyl Group
