Question

What type of molecule is shown below?

Answer 1

Hint: The basic concept of organic chemistry tells us about the type of amines attached to the hydrocarbons that is whether primary, secondary and tertiary amines and the answer lies in this fact.

Complete step by step answer:
From the previous classes of organic chemistry which deals with the chapters of organic synthesis and mechanisms, IUPAC names of the compounds and also to determine the type of the carbon atoms that are primary, secondary or tertiary and also about the amines.
Let us now see what type of molecule is the given one in the question.-
- The structure of the molecule shows that one amine group that is $-N{{H}_{2}}$ group is attached to the carbon which is further extended by the alkyl chains.
- Primary amines are those in which one hydrogen atom attached to nitrogen in the ammonia molecule is replaced by the alkyl chain and the formula of ammonia will change to $R-N{{H}_{2}}$ where R is the alkyl group.
- Secondary amines are those when two hydrogen atoms of ammonia are replaced by the alkyl chains and the formula changes to $R-NH-{{R}^{'}}$
- The tertiary amines are formed when all three hydrogen atoms of ammonia are replaced by the alkyl groups and the formula will be,
           

Therefore, based on the above facts, the given molecule is the primary amine that is $-N{{H}_{2}}$ group is attached to the alkyl group.

Note: Note that in case of carbon which has valency of 4, when one hydrogen of methane is replaced by other alkyl or aryl groups then that is primary carbon and similarly, the secondary and tertiary carbons have two and three hydrogens replaced respectively and additional quaternary carbon is formed when all the 4 hydrogens are replaced.
