Accepted Answer

1) 3,4-diethyl-2,5-dimethylheptane

a) The longest continuons chain of C atoms: 7 ⇒ heptane

b) Green chain: 3 substituents; Blue chain: 4 substituents ⇒Blue chain is the main chain

c) Number the C atoms of the longest chain in order to get the smallest Σ

2)

3) The chemical formula for the two compound is C₁₃H₂₈; therefore these two molecules are constitutional isomers.
