Question

what is the iupac name of the compound below? ch3—ch2—c(ch3)(ch2ch3)—ch2ch2—c(sh)(ch2ch3)—ch2ch2ch2ch3 3,6 - diethyl - 3 - methyl - 8 - decathiol 3,6 - diethyl - 3 - methyl - 8 - decanethiol 5,8 - diethyl - 8 - methyl - 5 - decanethiol 5,8 - diethyl - 8 - methyl - 5 - decathiol 3 - butyl - 6 - ethyl - 6 - methyl - 3 - octanethiol

Explanation:

Step1: Identify the longest carbon - chain

The longest carbon - chain has 10 carbon atoms, so the parent name is decane. Since it is a thiol ( - SH group), the suffix is - anethiol.

Step2: Number the carbon - chain

Number the carbon - chain in a way that the - SH group gets the lowest number. Starting from the end closest to the - SH group, the - SH group is on the 8th carbon.

Step3: Identify and number the substituents

There are two ethyl groups ( - CH₂CH₃), one at the 3rd and one at the 6th carbon, and one methyl group ( - CH₃) at the 3rd carbon.

Answer:

3,6 - diethyl - 3 - methyl - 8 - decanethiol
