Question

a. nomenclature and structure

1. identify the compound names of the following:

○ a. ch₃ch₂sh
○ b. (ch₃)₂chsh
○ c. ch₃ch₂sch₂ch₃
○ d. ch₃sch₃

Explanation:

Step1: Naming thiols

Thiols are named by adding the suffix -thiol to the name of the parent alkane.
For \(CH_3CH_2SH\), the parent alkane is ethane. So its name is ethanethiol.
For \((CH_3)_2CHSH\), the parent alkane is propane. So its name is 2 - methylpropanethiol.

Step2: Naming sulfides

Sulfides are named by naming the two alkyl groups attached to the sulfur atom and then adding the word sulfide.
For \(CH_3CH_2SCH_2CH_3\), the two alkyl groups are ethyl groups. So its name is diethyl sulfide.
For \(CH_3SCH_3\), the two alkyl groups are methyl groups. So its name is dimethyl sulfide.

Answer:

a. Ethanethiol
b. 2 - methylpropanethiol
c. Diethyl sulfide
d. Dimethyl sulfide
