Question 8

NAMING CONVENTIONS
TRUE or FALSE: If a cycloalkane is a substituent, we do not consider the prefix -“cyclo” when arranging the substituents alphabetically.

Answer 8

FALSE, we do consider the prefix -”cyclo” when naming.

(For example: 2-cyclohexyl - 4-ethyl - 5,6-dimethyloctane)

Question 9

NAMING CONVENTIONS
TRUE or FALSE We consider the prefixes -“di”, -“tetra”, -“quadra”, -“penta” etc. when arranging substituents alphabetically.

Answer 9

FALSE. We do not consider these prefixes and instead focus on the ”core” prefixes.

(For ex: 1-tetrabutyl - 2-ethyl - 3,4,5-dimethylnonane)

Question 10

NAMING CONVENTIONS
TRUE or FALSE: When arranging a sec-butyl as a substituent, we do not consider the -“sec” part when arranging and instead focus on butyl.

Answer 10

TRUE
