Answer: 1. [skeletal structure - see figure]

Key idea: build the chain from the name: 10 carbons (dec), a double bond between C-4 and C-5, and methyl groups on C-2 and C-6.

In option 1, numbering from the isopropyl end: C-1 and a methyl on C-2, then C-3 (\(\mathrm{CH_2}\)), C-4=C-5, then C-6 carrying a methyl, followed by a butyl chain C-7 to C-10. This is 2,6-dimethyldec-4-ene.

Option 2 has the double bond near the ethyl end (wrong position) and the branch in the wrong place. Option 3 has the double bond at C-3. Option 4 has a methyl on a double-bond carbon.
