Answer to Problem 14.3P
The substitutive name of the given compound is
Explanation of Solution
The structure of the given compound is shown below.
Figure 1
The compound has five carbon atom in the longest chain. Therefore, pent- will be used in the root name. The number of the carbon atoms will be started from the carbon atom which gives the lowest number to hydroxyl group in the chain.
The number on the carbon atoms in the compound is shown below.
Figure 2
The compound has methyl group and hydroxyl group. Therefore, -yne will be present as primary suffix and –ol will be present on as secondary suffix. The methyl group is resent at the second carbon. Therefore, methyl will be used as prefix. The triple bond is present on the third carbon atom and hydroxyl group is present on the second carbon atom. Therefore, the substitutive name of the compound is
The substitutive name of the given compound is

Answer to Problem 14.3P
The substitutive name of the compound is
Explanation of Solution
The structure of the given compound is shown below.
Figure 3
The compound has seven carbon atom in the longest chain. Therefore, hept- will be used in root name. The number of the carbon atoms will be started from the carbon atom which gives lowest number to propyl group in the chain.
The number on the carbon atoms in the compound is shown below.
Figure 4
The compound has propyl group and methoxy group. Therefore, methoxy and propyl will be present as suffix. The propyl group is present at the third carbon. The triple bond is present on the first carbon atom and double bond is present at the fifth carbon atom. Therefore, the substitutive name of the compound is
