CH3 H,C_2______COOH CH IUPAC name is: 3,3-dimethylhexanoic acid Explanation: The number of carbon atoms in the longest carbon chain are 6 so the rootword is hex-. Two methyl groups are located at 3,3-positions and the functional group is carboxylic acid so the name is 3,3- dimethylhexanoic acid H3c— _62_62_COOH IUPAC name is: 4-chloropentanoic acid Explanation: The number of carbon atoms in the longest carbon chain are 5 so the rootword is pent-A- Cl group is located at 4th position and the functional group is carboxylic acid so the name is 4- chloropentanoic acid
CH2CH3 (H2CH2C)HC—?––COOH IUPAC name is: 2,4-diethylhexanoic acid Explanation: The number of carbon atoms in the longest carbon chain are 6 so the rootword is hex-. Two ethyl groups are located at 2,4-positions and the functional group is carboxylic acid so the name is 2,4- diethylhexanoic acid
