In allene (C3H4)\left(\mathrm{C}_{3} \mathrm{H}_{4}\right), the type(s) of hybridisation of the carbon atoms is (are):

Options

  1. Asps p and sp3s p^{3}
  2. Bsps p and sp2s p^{2}
  3. Conly sp3s p^{3}
  4. Dsp2s p^{2} and sp3s p^{3}

Correct answer

B. sps p and sp2s p^{2}

Step-by-step solution

Allene (C3H4)\left(\mathbf{C}_{3} \mathbf{H}_{4}\right) is H2sp2C=Csp=CH2sp2\stackrel{s p^{2}}{\mathrm{H}_{2}} \mathrm{C}=\stackrel{s p}{\mathrm{C}}=\stackrel{s p^{2}}{\mathrm{CH}_{2}}
