How many covalent bonds are there in CN^-?

Question

Quizplus · Accepted Answer

To determine the number of covalent bonds, we count the number of pairs of electrons shared between atoms. 
-CN has a triple bond, which accounts for 3 covalent bonds. 
-Each F-S and S-P bond accounts for 1 covalent bond each. 
-There are no covalent bonds with U because it does not form bonds. 
Adding them up, we get 3+1+1=5. However, the ion has one extra electron, giving a total of 6 electrons to distribute. Since each bond involves 2 electrons, we divide 6 by 2 to get 3 covalent bonds. Therefore, the answer is C.
