What is the hybridisation of ( Be ) in ( BeF ₂ ) molecule?

Options

  1. A(d s p^2 )
  2. B(s p^2 d )
  3. C( sp )
  4. D(s p^3 )

Correct answer

C. ( sp )

Step-by-step solution

Hybridisation state of ( Be ) in ( BeF ₂ ) is (s p ). ( aligned & F - Be - F & H = 1 2 (V+M-C+A) &= 1 2 (2+2-0+0)=2(s p) aligned ) where, (V= ) number of valence electrons of ( Be =2 ) (H= ) number of monovalent ( F ) atom (=2 ) (C= ) number of cationic charge (= 0 ) (A= ) number of anionic charge (=0 ) So, the hybridisation of ( Be ) in ( BeF ₂ ) molecule is (s p ).
