Among the following ethers, the one that will produce methyl alcohol on treatment with hot concentrated HI is:
| 1. |  |
2. |  |
| 3. |  |
4. |  |
Preparation of ethers by 2 or 3-degree alcohols in an acidic medium is not a suitable method because:
| 1. | In case of secondary or tertiary alcohols, ketone is obtained as a product. |
| 2. | In case of secondary or tertiary alcohols, aldehyde is obtained as a product. |
| 3. | In case of secondary or tertiary alcohols, alkene is obtained as a product. |
| 4. | In case of primary alcohols, alkene is obtained as a product. |
CH3 — O — CH(CH3)2 + HI → B (Product)
The product 'B' in the above mentioned reaction is-
1. CH3OH + (CH3)2CHl
2. lCH2OCH(CH3)2
3. CH3OC(CH3)2
4. CH3l + (CH3)2CHOH
