P SRAVAN KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: IUPAC Nomenclature of Ethers
	**Related Topics**: Alkyl groups, Functional groups, Organic Chemistry
	**Prerequisites**: Understanding of ether structure and IUPAC naming rules.
## SOLUTION PATHWAY
**Given Information**:
	The compound is $CH_3CH_2OCH(CH_3)_2$. This represents an ether.
**Method & Steps**:
	1. **Identify the two alkyl groups attached to the oxygen atom.**
		Reasoning: Ethers are named as alkoxy alkanes. We need to identify the smaller and larger alkyl groups.
	2. **Name the smaller alkyl group attached to the oxygen as an alkoxy group.**
		Working: $CH_3CH_2-$ is an ethyl group. When attached to oxygen, it becomes 'ethoxy'.
		Key Point: The smaller alkyl group forms the alkoxy part of the name.
	3. **Name the larger alkyl group as an alkane.**
		Working: $CH(CH_3)_2$ is an isopropyl group. The corresponding alkane is propane. Therefore, it's named 'isopropane'.
		Key Point: The larger alkyl group forms the alkane part of the name.
	4. **Combine the alkoxy and alkane names.**
		Result: 'Ethoxyisopropane'
		Verification: This follows the IUPAC nomenclature rules for ethers.
## OPTION ANALYSIS
[A] ✓: 'Ethoxyisopropane': Correct as explained above. The smaller group (ethyl) becomes 'ethoxy' and the larger group (isopropyl) becomes 'isopropane'.
[B] :x: '2-Ethoxypropane':  While the 'ethoxy' part is correct, the isopropyl group is already part of the propane name, so numbering isn't necessary.  'Isopropane' is preferred over '2-propane' in this context.
[C] :x: '1-Ethoxy-1-methylethane': This names the compound as a substituted ethane. However, it's clearer and more correct to name it as an ether (alkoxyalkane) due to the presence of the $C-O-C$ functional group.  
[D] :x: 'Isopropoxyethane': This reverses the order of naming. The smaller alkyl group (ethyl) should be named as the alkoxy substituent ('ethoxy'), and the larger alkyl group (isopropyl) should form the base alkane name ('isopropane').
## LEARNING AIDS
	**Common Mistakes**:
		1. Incorrectly numbering the alkane chain when an iso-group is present:  Avoid numbering when the iso-group itself defines the position (as in isopropane). 
		2. Reversing the order of naming the alkoxy and alkane parts: Remember the smaller group is the alkoxy part.
	**Quick Tips**:
		1. Identify the $C-O-C$ functional group to recognize it as an ether.
		2. Remember the general naming format: (smaller alkyl group)-oxy-(larger alkyl group)ane.
