(a)
Interpretation:
The structure of six-membered cyclic hemiacetal formed by 5-hydroxyhexanal should be drawn.
Concept Introduction:
Hemiacetal is a molecule formed by the addition of an alcohol to an
Answer to Problem 17.71P
Explanation of Solution
Reaction of the aldehyde group and the hydroxyl group forms a six-membered cyclic hemiacetal.
Therefore, the structure hemiacetal formed from 5-hydroxyhexanalis as follows:
(b)
Interpretation:
The number of possible stereoisomers of 5-hydroxyhexanal should be determined.
Concept Introduction:
Stereoisomers are the compounds that are differ only in the spatial arrangements of their atoms. For a molecule with n stereoisomers, a maximum of
Answer to Problem 17.71P
5-hydroxyhexanal has 2 stereoisomers.
Explanation of Solution
For a molecule with n stereoisomers, a maximum of
In 5-hydroxyhexanal, there is one stereocenter.
Therefore, number of stereoisomers can be calculated as follows:
Thus, number of stereoisomers will be 2.
(c)
Interpretation:
The number of possible stereoisomers of hemiacetal of 5-hydroxyhexanal should be calculated.
Concept Introduction:
Stereoisomers are the compounds that are differ only in the spatial arrangements of their atoms. For a molecule with n stereoisomers, a maximum of
Answer to Problem 17.71P
Hemiacetal of 5-hydroxyhexanal has 4 stereoisomers.
Explanation of Solution
For a molecule with n stereoisomers, a maximum of
In hemiacetal of 5-hydroxyhexanal, there are two stereo centres.
Therefore, number of stereoisomers can be calculated as follows:
Thus, number of stereoisomers are 4.

- The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes.
