Interpretation:
Structure of the 3-hexanol should be drawn.
Concept Introduction:
Alcohols are the organic molecules which have OH group bonded to a tetrahedral carbon atom.
Longest carbon chain containing the carbon bonded to the OH group is named as an
Numbering of main carbon chain is done in such a way so that OH group gets the lowest number.
When OH group is bonded to a ring, the ring is numbered beginning with the OH group and the 1 is normally omitted from the name. The ring is numbered in clockwise or anticlockwise by giving the lowest number to the next substitute.
Compounds which contains two OH groups are named as
Answer to Problem 39P
Explanation of Solution
Structure of the 3-hexanol contains six carbon length main carbon chain which connects to an alcohol group in the 3rd carbon of the main carbon chain. There are no sub groups which connect to it. And according to the structure it should be a secondary alcohol.
According to the name, structure of the compound is as below;
(b)
Interpretation:
Structure of the propyl alcohol should be drawn.
Concept Introduction:
Alcohols are the organic molecules which have OH group bonded to a tetrahedral carbon atom.
Longest carbon chain containing the carbon bonded to the OH group is named as an alkane and -e of the alkane replaced by the suffix -ol.
Numbering of main carbon chain is done in such a way so that OH group gets the lowest number.
When OH group is bonded to a ring, the ring is numbered beginning with the OH group and the 1 is normally omitted from the name. The ring is numbered in clockwise or anticlockwise by giving the lowest number to the next substitute.
Compounds which contains two OH groups are named as diols and when in nomenclature, -diol suffix is added to the end of the parent alcohol and position of the OH groups are used as prefix to indicate the location of the two OH groups.
Answer to Problem 39P
Explanation of Solution
Structure of the propyl alcohol consist one main C chain which contains three C atoms, and alcohol group is connected to the 3rdposition of the main C chain. As per the name it should be a primary alcohol.
Structure of the compound is as below;
(c)
Interpretation:
Structure of the 2-methylcyclopropanol should be drawn.
