Chapter 1: Problem 33

The IUPAC name of the compound given is (a) \(2,2-\) diethyl propane \(-1,3-\) dialdehyde (b) 3,3 - diethyl pentane- 1,5 -dial (c) \(2,2-\) diethyl propane \(-1,3-\) dial (d) 3,3 -dimethyl keto pentane

Short Answer

Expert verified
Answer: The correct IUPAC name for the given compound is 3,3-diethyl pentane-1,5-dial.

Step by step solution

01

Analyze the choices

Let us analyze each option given: (a) \(2,2-\) diethyl propane \(-1,3-\) dialdehyde (b) 3,3 - diethyl pentane- 1,5 -dial (c) \(2,2-\) diethyl propane \(-1,3-\) dial (d) 3,3 -dimethyl keto pentane To solve this exercise, we should recall the rules for IUPAC nomenclature and identify the functional groups in the compound. In this case, there are two main types of functional groups to consider: aldehyde and ketone groups.
02

Identify the incorrect choices

First, we should exclude incorrect options based on the functional groups: - Option (a) and (c) mention "diethyl propane," which implies an aliphatic compound without an aldehyde or ketone group. Hence, these options are incorrect. - Option (d) mentions "keto pentane," which implies a ketone compound. However, there is no indication of a second functional group.
03

Analyze the correct choice

The correct option should be the one that correctly describes the structure of the compound with the relevant functional groups mentioned. - Option (b) 3,3-diethyl pentane- 1,5 -dial: This option describes a compound with an aldehyde group on both ends of the pentane structure (1,5 position). It also mentions the presence of diethyl groups at the 3,3 positions. Since option (b) correctly describes the compound's structure and functional groups, it is the correct answer.
04

Final Answer

The correct IUPAC name for the given compound is: (b) 3,3 - diethyl pentane- 1,5 -dial.
