How many of the following is/are not optically active amine? (I) `CH_3NH_2`
(II) `CH_3 NHCH_3` (III) `CH_3CH_2CH_2N(CH_3)C_2H_5` (IV) Secondary butylamine
Text Solution
AI Generated Solution
To determine how many of the given amines are not optically active, we need to analyze each compound for the presence of a chiral center. A chiral center is typically a carbon atom bonded to four different groups. In the case of amines, a nitrogen atom can also serve as a chiral center if it is bonded to three different groups and has a lone pair.
Let's analyze each compound step by step:
### Step 1: Analyze `CH3NH2` (Methylamine)
- Structure: `CH3-NH2`
- The nitrogen atom is bonded to:
- One methyl group (`CH3`)
