What type of isomerism is exhibited by neopentane?

Options

  1. Aposition
  2. Bchain
  3. Cgeometrical
  4. Dtautomerism

Correct answer

B. chain

Step-by-step solution

Neopentane ( C₅H₁₂ ) is an isomer of pentane. The isomers of pentane are n-pentane, isopentane, and neopentane. These compounds have the same molecular formula but differ in the arrangement of their carbon skeleton (straight chain versus branched chain). Therefore, neopentane exhibits chain isomerism. Answer: chain
