Answer 1

2-methylheptane , one n-propane chain

3-methylheptane , no propane chain

3-methylheptane, no propane chain

2,3-dimethylhexane , one propane chain

2,4-dimethylhexane, one propane chain

2,5- dimethylhexane,two propane chain

3,4-dimethylhexane, no propane chain

2,2-dimethylhexane,three propane chain

3,3-dimethylhexane , one propane chain

3-ethylhexane, no propane chain

2,3,4-trimethylpentane, two propane chain

2,2,3-trimethylpentane,three propane chain

2,3,3-trimethylpentane , two propane chain

2,2,4-trimethylpentane, four propane chain

3-ethyl-2-methylpentane, one propane chain

3-ethyl-3-methylpentane, no propane chain

2,2,3,3-tetramethylbutane , six propane

2,5-dimethylhexane ,  2,2-dimethylhexane , 2,3,4-trimethylpentane , 2,2,3-trimethylpentane , 2,3,3-trimethylpentane , 2,2,4-trimethylpentane , 2,2,3,3-tetramethylbutane this alkanes have two equivalent n-propyl branches
