Answer 1

CH2CH3 H3CH2C_6-CH2CH3 IUPAC name is: 3-ethylpentane Explanation: The number of carbon atoms in the longest carbon chain are 5 so the rootword is pent- An ethyl group is located at 3rd position so the name is 3-ethylpentane CHE H2C— C—CH CH3 CHE IUPAC name is: 2,2-dimethylbutane Explanation: The number of carbon atoms in the longest carbon chain are 4 so the rootword is but-. Two methyl groups are located at 2.2-positions so the name is 2,2-dimethylbutane

Hąc— —CH2CH2 H3CH2CH2CH2C— C—CH2CH2CH2CH2CH3 IUPAC name is: 5-(sec-butyl)decane Explanation: The number of carbon atoms in the longest carbon chain are 10 so the rootword is dec-. A sec-butyl group is located at 5th position so the name is 5-(sec-butyl)decane CH3 CH3 Hyc——& H3C—C—CH3 —5—ch,CHCH3 CH3 IUPAC name is: 5-tert-butyl)-2,3-dimethyloctane Explanation: The number of carbon atoms in the longest carbon chain are 8 so the rootword is oct-. A tert- butyl group is located at 5th position and two methyl groups are located at 2,3-positions so the name is 5- (tert-butyl)-2,3-dimethyloctane
