(a)
Interpretation:
The name of the given branched alkane has to be given.
Concept Introduction:
Alkanes can be classified as-
- Straight-chain alkanes
- Branched-chain alkanes
(a)
Answer to Problem 16A
The name of the compound is 4,5-dimethylnonane.
Explanation of Solution
Here the parent chain is nonane and two methyl groups are attached to 4 and 5 position. So, the name of the compound is 4,5-dimethylnonane
(b)
Interpretation:
The name of the given branched alkane has to be given.
Concept Introduction:
Alkanes are the saturated hydrocarbons which contain only C-H and C-C single bonds. The general formula of alkane is CnH2n+2. The simplest alkane among all alkanes is methane CH4.
Alkanes can be classified as-
- Straight-chain alkanes
- Branched-chain alkanes
(b)
Answer to Problem 16A
The name of the compound is 3,3,4,4-tetramethylheptane.
Explanation of Solution
Here the parent chain is heptane and two methyl groups are attached to 3rd carbon and other two methyl groups are attached to 4thcarbon.So, the name of the compound is 3,3,4,4-tetramethylheptane
The compound is 2,3,4-trimethylhexane
(c)
Interpretation:
The name of the given branched alkane has to be given.
Concept Introduction:
Alkanes are the saturated hydrocarbons which contain only C-H and C-C single bonds. The general formula of alkane is CnH2n+2. The simplest alkane among all alkanes is methane CH4.
Alkanes can be classified as-
- Straight-chain alkanes
- Branched-chain alkanes
(c)
Answer to Problem 16A
The name of the compound is 3,4,5,5-tetramethyloctane.
Explanation of Solution
Here the parent chain is octane and two methyl groups are attached to 3 and 4 position and two methyl groups are attached to 5th carbon. So, the name of the compound is 3,4,5,5-tetramethyloctane
(d)
Interpretation:
The name of the given branched alkane has to be given.
Concept Introduction:
Alkanes are the saturated hydrocarbons which contain only C-H and C-C single bonds. The general formula of alkane is CnH2n+2. The simplest alkane among all alkanes is methane CH4.
Alkanes can be classified as-

(d)
Answer to Problem 16A
The name of the compound is 2,3,4-trimethylhexane.
Explanation of Solution
Here the parent chain is hexane and three methyl groups are attached to 2, 3 and 4 position in the parent chain. So, the name of the compound is 2,3,4-trimethylhexane

This quiz is open textbook / open notes - but you must work alone. You cannot use the internet or the solutions manual for the book. Scan in your work and record an explanation of your mechanism. You may record this any way that you like. One way would be to start an individual Zoom meeting, start recording, "share your screen" and then talk through the problem. This will be converted to an .mp4 file that you can upload into Canvas using the "record/upload media" feature. Pyridine, benzoic acid and benzene are dissolved in ethyl acetate. Design and provide a plan / flow chart for separating and isolating each of these components. Pyridine and benzene are liquids at room temperature. Benzoic acid is a solid. You have ethyl acetate, 2M NaOH, 2M HCI and anhydrous MgSO4 available, as well as all the glassware and equipment that you used in the organic lab this year.
