MCQ
The hybrid orbitals used by central atoms in $BeC{l_2},\,\,BC{l_3}$ and $CC{l_4}$ molecules are respectively
- A$s{p^2},\,\,s{p^3}$ and $sp$
- ✓$s{p^{}},\,\,s{p^2}$ and $s{p^3}$
- C$s{p^2},\,\,s{p^3}$ and $s{p^2}$
- D$s{p^2},\,\,sp$ and $s{p^3}$
✓
Answer
Correct option: B.
$s{p^{}},\,\,s{p^2}$ and $s{p^3}$
b
The bond angle of $sp _3$ is $109.5, sp _2$ is $120$ and $sp$ is $180$ . An $sp$ orbital is half $s$ character, $sp _2$ is $\frac{1}{3} s$ character and $sp _3$ is $\frac{1}{4} s$ character, so increasing the $s$ character corresponds to increasing the bond angle.
