In acetylene molecule, $\mathrm{C}-\mathrm{H}$ sigma bond is formed by

In acetylene molecule, $\mathrm{C}-\mathrm{H}$ sigma bond is formed by
  1. s - p overlap
  2. sp - s overlap
  3. $\mathrm{p}-\mathrm{p}$ overlap
  4. sp - sp overlap

Solution

$\underset{\mathrm{S}}{\mathrm{H}}-\underset{\mathrm{SP}}{\mathrm{C}} \equiv \underset{\mathrm{SP}}{\mathrm{C}}-\underset{\mathrm{S}}{\mathrm{H}}$
