Make up the structural formulas of 3-methylhexene-2 3,4-diethyl octane.

1) 3-methylhexene-2. The “hexene-2” part says that it is an alkene of 6 carbon atoms. As you know, there is a double bond in alkenes. In this case, it is located after the second C atom. The formula has a methyl radical CH3, which departs from the third carbon atom. CH3-CH = C (CH3) -CH2-CH2-CH3
2) 3,4-diethyl octane. “Octane” means that it is an alkane of 8 carbon atoms. Alkanes can only have a single bond. The formula has two ethyl radicals C2H5 located under the third and fourth C atoms. CH3-CH2-CH (C2H5) -CH (C2H5) -CH2-CH2-CH2-CH3.
