HSC Chemistry — Module 7
Organic Nomenclature — Flashcards & Quiz
Organic nomenclature is the systematic naming of carbon compounds following IUPAC rules. HSC Chemistry Module 7 requires you to name and draw structures for alkanes, alkenes, alkynes, alcohols, aldehydes, ketones, carboxylic acids, amines, amides, and esters. You must identify the longest carbon chain, locate substituents, and number correctly. Exam questions test naming from structures and drawing structures from names, often including isomers. Mastering nomenclature is essential because it underpins every other organic chemistry topic in the module.
Sample Flashcards
Q1: How do you name organic compounds using IUPAC nomenclature?
1) Find the longest carbon chain (parent chain). 2) Name the parent chain: meth-, eth-, prop-, but-, pent-, hex- etc. 3) Add suffix for functional group: -ane (alkane), -ene (alkene), -ol (alcohol), -al (aldehyde), -one (ketone), -oic acid (carboxylic acid). 4) Number the chain to give substituents the lowest numbers. 5) Name substituents with position numbers.
Q2: Name the first 8 prefixes in IUPAC naming.
meth- (1C), eth- (2C), prop- (3C), but- (4C), pent- (5C), hex- (6C), hept- (7C), oct- (8C). These prefixes indicate the number of carbons in the longest continuous chain (parent chain).
Sample Quiz Questions
Q1: The prefix "prop-" indicates a three-carbon chain.
Answer: TRUE
IUPAC prefixes: meth- (1C), eth- (2C), prop- (3C), but- (4C), pent- (5C), etc.
