(a) Interpretation: The given electronic configuration belongs to which neutral atom needs to be predicted. Whether it is for ground state or excited state needs to be identified. Concept introduction: According to Aufbau principle electrons are filled first in lower energy orbitals followed by higher energy orbitals. Hund’s rule states that while filling electrons in degenerate orbitals there will be single occupancy first and then only pairing can take place.

Predicting the pr
Predict the major products of the following organic reaction:

Some important notes:
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
