Question

Which of the following has been arranged in increasing order of size of the hybrid orbitals ?

• A. $sp<s{p}^2<s{p}^3$
• B. $s{p}^3<s{p}^2<sp$
• C. $s{p}^2<s{p}^3<sp$
• D. $s{p}^2<sp<s{p}^3$

Answer 1

The correct option is A $sp<s{p}^2<s{p}^3$

As the $p-$ character in hybrid orbital increases, the size of hybrid orbital increases.
The $\%$ p - character in $sp$ orbital is 50%
The $\%$ p - character in $s{p}^2$ orbital is 66.66%
The $\%$ p - character in $s{p}^3$ orbital is 75%
