What can be stated about the name, 4-Methylpentane? (Hint: Draw the molecule from the name given and then try to rename it.)


A) 4-Methylpentane is a valid name for a compound.
B) This name is wrong because the longest chain is six carbon atoms in length. It should be named Hexane.
C) This name is wrong because it does not provide the lowest number for the substituent "Methyl" group. It should be named 2-Methylpentane.
D) This name is wrong because the substituent group is "isopropyl" and the compound name should be 1-Isopropylpropane.
E) This name is wrong because it doesn't take into account that there are two methyl substituents at the branch point and the compound should be named 1,1-Dimethylbutane.
