Sec – Butylamine is the common name of what compound?a)2 –...
Explanation:
Common names of organic compounds are given based on their structure or origin. In this case, the compound given is sec-butylamine. Let's break down the name to understand its structure.
- The first part of the name is "sec", which stands for secondary. This means that the amine group (-NH2) is attached to the second carbon atom in the parent chain.
- The second part of the name is "butyl", which refers to the four-carbon chain (C4H9) attached to the amine group.
- The third part of the name is "amine", indicating that the compound is an amine, i.e. a derivative of ammonia (NH3) in which one or more hydrogen atoms are replaced by alkyl groups.
Therefore, sec-butylamine has the following structure:
CH3CH(CH3)CH2NH2
Now, let's look at the options given and determine which one corresponds to sec-butylamine.
- Option A: 2-butanamine - This compound has the same structure as sec-butylamine. The prefix "2" indicates that the amine group is attached to the second carbon atom in the chain, which is also the case for sec-butylamine. Therefore, option A is correct.
- Option B: N-ethylethanamine - This compound has a two-carbon chain (ethyl) attached to the nitrogen atom, which is different from the four-carbon chain in sec-butylamine. Therefore, option B is incorrect.
- Option C: 1-butanamine - This compound has the amine group attached to the first carbon atom in the chain, which is different from the second carbon atom in sec-butylamine. Therefore, option C is incorrect.
- Option D: N-methyl-1-propanamine - This compound has a three-carbon chain (propyl) and a methyl group attached to the nitrogen atom, which is different from the four-carbon chain in sec-butylamine. Therefore, option D is incorrect.
In conclusion, the common name for the compound given is sec-butylamine, which corresponds to option A.
