Determine the total number of allylic hydrogen atoms present in one molecule of 2,5-Dimethylhex-2-ene.

Step-by-step solution

First, draw the structure of 2,5-Dimethylhex-2-ene based on its IUPAC name: CH₃-C(CH₃)=CH-CH₂-CH(CH₃)-CH₃ . Identify the sp^2 hybridized carbon atoms of the double bond, which are C2 and C3. Allylic carbons are the sp^3 hybridized carbon atoms directly attached to the sp^2 carbons. In this molecule, the allylic carbons are C1, the methyl group attached to C2, and C4. Count the hydrogen atoms on these allylic carbons: 3 (from C1) + 3 (from the C2 methyl group) + 2 (from C4) = 8 allylic hydrogens. Counting only the v
