What is the bond order for the carbon-nitrogen bond in acetonitrile, ch3cn? 2.2.0 03.0.5 c. 3.0 d. 1.5 0.1.0

C. 3.0

Explanation:

To determine the bond order between carbon and nitrogen in acetonitrile, we need to consider the Lewis structure.

N has 5 valence electrons, so it shares 3 pairs of electrons to reach the octet.

C has 4 valence electrons, so it shares 4 pairs of electrons to reach the octet.

As we can see, in the Lewis structure there is a triple bond between C and N. The corresponding bond order is 3.0.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
