Four statements ethers are given below. Identify the FALSE statements .
(i) Ethers are named as alkoxy derivatives of alkane .
(ii) The larger alkyl group along with oxygen atom is named as alkoxy groups .
(iii) The larger alkyl group is considered as the parent alkane.
(iv) The position of the alkoxy group is indicated by the maximum number .

Options

A. (i) and (iii)
B. (ii) and (iv)
C. (ii) and (iii)
D. (i) and (iv)

Answer

To identify the false statements about ethers from the given options, let's analyze each statement step by step.

### Step 1: Analyze Statement (i)
**Statement (i):** Ethers are named as alkoxy derivatives of alkanes.

- **Analysis:** This statement is true. Ethers are indeed named as alkoxy derivatives of alkanes, where one alkyl group is named as an alkoxy group (the smaller one) and the other is considered the parent alkane (the larger one).

### Step 2: Analyze Statement (ii)
**Statement (ii):** The larger alkyl group along with the oxygen atom is named as alkoxy groups.

- **Analysis:** This statement is false. In ethers, the smaller alkyl group is named as the alkoxy group, while the larger alkyl group is considered the parent alkane. Therefore, this statement is incorrect.

### Step 3: Analyze Statement (iii)
**Statement (iii):** The larger alkyl group is considered as the parent alkane.

- **Analysis:** This statement is true. In the nomenclature of ethers, the larger alkyl group is indeed considered the parent alkane.

### Step 4: Analyze Statement (iv)
**Statement (iv):** The position of the alkoxy group is indicated by the maximum number.

- **Analysis:** This statement is false. The position of the alkoxy group is indicated by the lowest possible number in the carbon chain, not the maximum. Therefore, this statement is incorrect.

### Conclusion
Based on the analysis:
- **False Statements:** (ii) and (iv)

### Final Answer
The false statements are:
- (ii) The larger alkyl group along with the oxygen atom is named as alkoxy groups.
- (iv) The position of the alkoxy group is indicated by the maximum number.
