Interpretation : The general trend in first ionization energies in group 2 is to be described and explained.
Concept Introduction : Ionization energy is the bare minimum of energy that an electron in a gaseous atom or ion needs absorb to escape from the nucleus. The elements of group 2 have two valence electrons.
The first ionization energies in group 2 elements usually decrease down the group.
The elements of group 2 include beryllium, magnesium, calcium, strontium, barium, and radon.
The group 2 elements are also called alkaline earth metals.
The ionization energy usually decreases down the group.
The
Outermost electrons can be easily removed because they are far from the nucleus.
Moving down a group, the shielding effect brought on by an expanding number of shells is the second reason that lowers the ionization energy.

- Consider the molecule A,B, C and D shown below, (1 x 4) Br NH2 A OH Br 边 H B C D 1. Assign the R/S configuration to each chiral center and identify by circling all the chiral centers. 2. Draw an image for the enantiomer of each of the compounds A, B, C and D.arrow_forwardCould you crystallize one enantiomer of mandelic acid from a racemic mixture (using the typical achiral solvents found in our lab) without preparing a diastereomeric salt? Why or why not? No, because both enantiomers have the same solubility in achiral solvents. than the other. ооо Yes, because one enantiomer has a higher melting point No, because both enantiomers are liquids. Yes, because one enantiomer is more crystalline than the other.arrow_forwardIf the literature value of specific rotation for a chiral compound is -53.6°, what is the enantiomeric excess of a compound with a measured specific rotation of -40.5°?arrow_forward
- The process to determine the configuration, starts by placing the lowest priority substituent toward the back. If the substituents pointing forward decrease in priority in a clockwise order, the configuration is S. If the substituents decrease in priority in a counterclockwise order, the configuration is R.
