Which of the following has a bond formed by overlap of $s p-s p^3$ hybrid orbitals?

• Correct answer
  A

  $\mathrm{CH}_3-\mathrm{C} \equiv \mathrm{C}-\mathrm{H}$
• B

  $\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_3$
• C

  $\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_2$
• D

  $\mathrm{HC} \equiv \mathrm{CH}$

Solution

Hence, $\mathrm{CH}_3-\mathrm{C} \equiv \mathrm{C}-\mathrm{H}$ has a bond formed by overlap of $s p-s p^3$ hybrid orbitals.

Hence, the correct answer is option: 'A'.
