Which of the following compounds contain at least one (tertiary) carbon atom? — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

A $3^\circ$ carbon is bonded to three other carbons. Isobutane ($CH_3-CH(CH_3)-CH_3$) has one $3^\circ$ carbon. 2,3-dimethylbutane has two $3^\circ$ carbons. Neopentane and 2,2-dimethylbutane lack $3^\circ$ carbons (possessing $4^\circ$ instead).
