Given four chemical bonds, Determine if each of the statement is True or False.

Question

C―Si    C=C     C≡N   C=N

1) There are three bonding pairs between C and N in a C≡N bond. ["True", "False"]      

 

2) The C=O bond is stronger than the C=N bond because O is larger than N. ["False", "True"]    

     

3) The order of increasing bond length is: C≡N < C=N < C=C < C―Si. ["False", "True"]       

4) The only reason that the C=C bond is shorter than the C―Si bond is that a C atom is smaller than a Si atom. ["True", "False"]       

Answer 1

1) There are three bonding pairs between C and N in a C≡N bond. ["True", ]      

 

2) The C=O bond is stronger than the C=N bond because O is larger than N. ["False",]    

     

3) The order of increasing bond length is: C≡N < C=N < C=C < C―Si. [ "True"]       

4) The only reason that the C=C bond is shorter than the C―Si bond is that a C atom is smaller than a Si atom. [ "False"]
