What is the percent s character in an sp? hybridized orbital? 25% 33% 50% 67% 75%

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 % .
