đ Key Concepts
⢠Chemical families used in marine hazardous materials questions (e.g., alcohols, esters, ethers, allyl compounds)
⢠How functional groups (like âOH, âOâ, double bonds, halogens) determine which family a compound belongs to
⢠Relationship between name endings in organic chemistry and their typical families (e.g., -ol, -ate, -yl, -ether)
đ Think About
⢠Look at each choice and recall the defining functional group or structural feature of that family; which one best matches how a compound named "chlorallylene" would likely be built?
⢠Think about whether the name suggests an âOH group, an âOâ linkage between carbons, a double bond (allyl-type structure), or something else.
⢠Ask yourself: does the root of the word look more like an alcohol, an ester, an ether, or a substituted allyl compound?

Before You Answer
⢠Before choosing, be sure you recall that alcohols contain an âOH group and often end in -ol.
⢠Verify that esters usually end in -ate or -oate and involve a COO linkage between carbon atoms.
⢠Remember that ethers (and glycol ethers) have a CâOâC linkage, while allyl-based compounds involve a carbonâcarbon double bond adjacent to another carbon.
