(a)
Interpretation: Below drawn alkane should be named using the IUPAC system.
Concept Introduction: Organic compounds containing single-bonded Carbon and Hydrogen atoms are
Formula for Alkane is CnH2n+2
(a)
Answer to Problem 3SP
IUPAC name is 1-methyl, 3-ethyl pentane.
Explanation of Solution
Alkane containing 5 Carbon atoms has n=5.
Substituting n=5 in the molecular formula for Alkane (CnH2n+2), we get C5H12.
Molecule of Pentane with Methyl group (-CH3) and Ethyl group (-CH2-CH3) are replacing Hydrogen atoms on Carbon atoms 1 and 3 respectively.
Therefore, the IUPAC name is 1-methyl, 3-ethyl pentane.
(b)
Interpretation: Below drawn alkane should be named using the IUPAC system.
Concept Introduction: Organic compounds containing single-bonded Carbon and Hydrogen atoms are Alkanes.
Formula for Alkane is CnH2n+2
(b)
Answer to Problem 3SP
IUPAC name is 3 methyl butane
Explanation of Solution
Alkane containing 4 Carbon atoms has n=4.
Substituting n=4 in the molecular formula for Alkane (CnH2n+2), we get C4H10.
Molecule of Butane with Methyl group (-CH3) is replacing Hydrogen atoms on Carbon atoms 3.
Therefore, the IUPAC name is 3 methyl butane.
