Question

Total number of a and k bonds in the structure of $ {{P}_{3}}{{O}_{10}} $ are:

• A. $ 12\sigma ,6\pi $
• B. $ 6\sigma ,10\pi $
• C. $ 18\sigma ,6\pi $
• D. $ 16\sigma ,4\pi $

Answer 1

Answer: (D)

P (atomic number = 15) $ =1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{3}} $ Structure of $ {{P}_{4}}{{O}_{10}} $
Thus, number of a bonds =16 and number of n bonds = 4
