Step 1:
I'll solve this Lewis structure problem step by step:

Step 2:
: Determine the total number of valence electrons

- Total valence electrons: $$(4 \times 4) + (10 \times 1) = 16 + 10 = 26$$ valence electrons
- Carbon (C) has 4 valence electrons - Hydrogen (H) has 1 valence electron

Step 3:
: Identify possible carbon skeleton arrangements

- C^4H^10 can have two possible structural isomers:

Step 4:

Straight-chain (n-butane)

Step 5:

Branched-chain (isobutane)

Step 6:
: Draw Lewis structure for n-butane

\begin{array}{c}
- Connect carbons in a linear chain - Attach hydrogens to fill octets - Distribute 26 valence electrons H-C-C-C-C-H \ | | | | \ H H H H \end{array}

Step 7:
: Draw Lewis structure for isobutane

\begin{array}{c}
- Create a branched carbon skeleton - Attach hydrogens to fill octets - Distribute 26 valence electrons \quad H \ \quad | \ H-C-C-C-H \ \quad | \quad | \ \quad H \quad H \end{array}

Final Answer

Two valid Lewis structures for C^4H^10 are n-butane and isobutane, each satisfying the requirements of no charged atoms and complete octets for carbon atoms.
