What a finished CHEM-120 Week 5 organic reaction explanation looks like
Around a page, with the equation present but never left to speak alone. The starting material is named and its relevant group identified. The reagent and the conditions get a line of their own, since the same compound under different conditions gives different products and an explanation that omits them has not explained the outcome. The product is then named under the same convention as the starting material. The center of the piece is a short passage saying which bond broke, which formed, and what is now attached where. A final paragraph reports the property that moved: an acid turned into an ester no longer dissolves the way it did, an alcohol turned into a carbonyl compound no longer offers a hydrogen to donate.
How a CHEM-120 Week 5 example is structured
Starting material, group, reagent and conditions, bond change, product, property. The group is identified before the reaction is described because the reaction happens to the group, and naming it first keeps the skeleton out of the account. Conditions sit early rather than as a footnote, since heat, acid, or an oxidizing agent is often the only thing distinguishing two outcomes from the same starting compound. The bond change is written atom by atom and takes more of the grade than everything around it: this bond broke, this one formed, this atom left with what. Naming the product follows, and the example keeps the convention it opened with. The last paragraph moves to behavior, which is where this course differs from a reaction inventory. A balanced equation sits alongside the prose where the classroom asks for one.
Name the group before the reaction
The reaction happens at a site, not to a whole molecule. Naming the group first keeps the skeleton out of the account and stops the answer describing the wrong thing.
Conditions are part of the answer
Heat, acid, an oxidizing agent. The same starting compound gives different products under different conditions, so an explanation leaving them out has not explained which product appeared.
Bond broken, bond formed
Written atom by atom. This passage carries more of the grade than anything around it, and it is the one most drafts compress into a single clause.
Same naming system at both ends
Reactant and product are named under one convention so a reader can hold them together. Switching partway leaves a grader checking whether two compounds are in fact one.
Say what changed about the compound
Solubility, boiling point, acidity, smell. The formula moved, and what the week is actually marked on is which of those moved with it.
Where marks go in CHEM-120 Week 5
The reaction named but never located takes the biggest share: oxidation announced with no word about which carbon carried it leaves a marker nothing to check. An equation pasted in and then read back in sentences costs almost as much, since the row wanted the account and got a translation. Losing the conditions is less visible and just as expensive, because two different products from the same starting material are often separated by nothing but heat or a reagent. Reaching for arrows and intermediates from a later course reads as borrowed and usually misplaces a step. Below those: a product named in one system and a reactant in another, a formula that does not balance, and an ending that stops at the product without saying what is different about it now.

The first one is free and is written to your own instructions rather than to a textbook example.
CHEM-120 Week 5 questions, answered
Does the explanation need a mechanism with arrows?
Rarely at this level, and reaching for one is a common overreach. A survey course asks which bond broke and which formed, not how electrons moved to get there. Where your section does teach arrows, follow its convention exactly, because a half-remembered mechanism is easier to mark wrong than a clear account of the change.
What if I cannot identify the product?
Work from the group rather than from memory. An alcohol treated with an oxidizing agent, an acid combined with an alcohol, a double bond meeting hydrogen: each has a standard outcome the textbook sets out, and naming the group narrows the possibilities to a handful. Guessing a product and explaining backward from it is visible immediately.
Should the equation be balanced?
Where the assignment shows equations, yes, and an unbalanced one is a quick and avoidable loss. Where the week is asking for prose, the equation is support rather than the answer, and it sits beside the sentences instead of replacing them. Either way the atoms on both sides match before anything is submitted.
