Question

which of the following compounds contain all 1°,2°,3° amine​

Answer 1

Answer:

Explanation:

B and c

Answer 2

Answer:

The Correct Answer would be the compound (B). The compound B in the given image contains all three types(1°, 2°, 3°) of amine.

Explanation:

What is meant by types of Amine?

Amine is a functional group in organic chemistry of form (-NH₂). It contains a Nitrogen atom attached to Carbon or Hydrogen atoms. Based on the number of Hydrogen/Carbon atoms attached, they are classified into three types.

• Primary Amine(1°) - In these amines, a nitrogen atom is bonded to two hydrogen atoms and one carbon atom. Example:

                                            CH₃-CH₂-NH₂.

• Secondary Amine(2°) - In the amines, a nitrogen atom is bonded to one hydrogen atom and two carbon atoms. Example:  

                                            CH₃-NH-CH₃.

• Tertiary Amine(3°) - In these amines, all the hydrogen atoms are replaced by carbon atoms. Example:  

                                             CH₃ - N - CH₃

                                                        |

                                                      CH₃

Now, in the given figure, we can see that only compound (B) shows all the three types (-NH₂, -NH-, -NCR-) at different places. Hence, it is the correct answer.
