Question
Which compound has the shortest C–N bond?
A. CH3NH2
B. (CH3)3CNH2
C. CH3CN
D. CH3CHNH
Solution
The length of a bond is determined by the size of the atoms and the type of bond (single, double, triple). In general, triple bonds are shorter than double bonds, which are shorter than single bonds. This is because more bonds between two atoms pull them closer together.
Looking at the options:
A. CH3NH2 - This has a single bond between C and N. B. (CH3)3CNH2 - This also has a single bond between C and N. C. CH3CN - This has a triple bond between C and N. D. CH3CH2NH2 - This has a single bond between C and N.
Therefore, the compound with the shortest C-N bond would be CH3CN because it has a triple bond between the carbon and nitrogen atoms.
