Question

In which of the above species, starred $C$ has $s{p}^2$ hybridisation?

• A. p, q
• B. p, q, r
• C. p, q, s, t
• D. q, s, t

Answer 1

The correct option is A p, q

$p:\begin{array}{ccccc}F& -& C& -& F\\ & & |& & \\ & & F& & \end{array}$ :- No. of bonds $=3$

$\Rightarrow s{p}^2$ hybridization.

$q:\begin{array}{ccccc}H& -& C& -& H\\ & & |& & \\ & & H& & \end{array}$ :- No. of bonds $=3$

$\Rightarrow s{p}^2$ hybridization.

$r:$ Since, $c$ atom is connected to $2$ double bonds

$\Rightarrow sp$ hybridization.

$s:$ No. of bonds $=3$

$1$ negative charge which is equivalent to a bond

$\Rightarrow s{p}^3$ hybridization.

$t:C$ is connected to $2$ double bonds

$\Rightarrow sp$ hybridization.
