🔍 Key Concepts
• Chemical families used in marine hazardous materials questions (e.g., alcohols, esters, ethers, allyl compounds)
• How functional groups (like –OH, –O–, 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)
💭 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 –OH group, an –O– 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 –OH 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 C–O–C linkage, while allyl-based compounds involve a carbon–carbon double bond adjacent to another carbon.
