Answer:
50%
Explanation:
The percent s - character , in a particular hybridization can be calculated from the following formula , i.e. ,
% s character = 1 / ( 1 + x ) * 100
Where , x = number of p orbitals .
Hence , from the question ,
The % s character in sp hybrid orbital is calculated as -
% s character = 1 / ( 1 + x ) * 100
x = 1 ( since , one p orbital is present in the sp hybridization )
% s character = 1 / ( 1 + 1 ) * 100
% s character = 1/ 2 * 100
% s character = 50 %.
Hence , the % s character in sp hybrid orbital = 50 % .
