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)  \[16\sigma ,4\pi \]               

Correct Answer: D

Solution :

                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
