Identify the longest, shortest, strongest, and weakest bonds from those highlighted below.
amm1812
Longest: D. Shortest: A. Strongest: A.  Weakest: D. 

Explanation: Answer choice A is the shortest and strongest. The greater number of bonds causes the electrons to be more compact and closer together. This makes the bond length short. Because the bond is tighter, it is also stronger.

Single bonds are the weakest and longest. So, now we must look at the difference between C and D. They're both C-C bonds, but the carbon bond in choice D is weaker because of the difference in p-character (hybridization).

Briefly explain why a proeutectoid phase (ferrite or cementite) forms along austenite grain boundaries. hint: consult section 4.
Gemiola [76]
<span>An interfacial energy is associated with the grain boundaries called as the grain boundary energy.

When a proeutectoid phase is formed along the already existing grain boundaries, there is an increase in the lower net interfacial energy, as when compared to the energy when the proeutectoid phase is formed within the interior of the grains.
