question_answer 1)

  The linear shape of \[C{{O}_{2}}\] is due to....... (a) \[s{{p}^{3}}\]-hybridisation of carbon                                              (b) \[sp\]hybridisation of carbon (c) \[p\pi -p\pi \]bonding between carbon and oxygen (d) \[s{{p}^{2}}\] -hybridisation of carbon

Answer:

  (b, c) In\[C{{O}_{2}}\], carbon is \[sp\]-hybridised. The hybrid orbitals form sigma bonds with p-orbitals of each oxygen atoms. The unhybridized two p-orbitals of carbon atom form two\[\pi \]-bonds with two oxygen atoms.
