Concept explainers
(a)
Interpretation:
The molecular orbital that holds the “extra electrons” in allyl anion is to be identified by using the molecular orbital diagram.
Concept introduction:
An allylic carbocation is a positively charged carbocation which is adjacent to a double bond. This carbocation is considered to be more stable as compared to branched non allylic alkyl carbocation allylic carbocations are stable because of their electronic structures.
(b)
Interpretation:
The carbon atom that bears the negative charge is to be identified according to the molecular orbital description.
Concept introduction:
An allylic carbocation is a positively charged carbocation which is adjacent to a double bond. This carbocation is considered to be more stable than branched non allylic alkyl carbocation allylic carbocations are stable because of their electronic structures.
(c)
Interpretation:
The same conclusion is to be shown by drawing resonance structures of allyl anion.
Concept introduction:
Resonance structures represent the delocalization of electrons. It is considered as a stabilizing effect. The energy associated with electron delocalization is known as resonance energy

Calculate the central, upper, and lower control limits for the c-chart and draw the chart precisely on the graph sheet provided (based on 3-sigma limits). Your chart should include a line for each of the control limits (UCL, CL, and LCL) and the points for each observation. Number the x-axis 1 through 25 and evenly space the numbering for the y-axis. Connect the points by drawing a line as well. Label each line drawn.
