Q. No.The compound having the lowest boiling point is:
| 1. | Ethanol | 2. | Methanol |
| 3. | Methoxymethane | 4. | Propanol |
The preferred alkyl halide for the synthesis of ether in Williamson synthesis is:
| 1. | Secondary | 2. | Tertiary and secondary both |
| 3. | Tertiary | 4. | Primary |
| 1. | 1-Propoxypropane | 2. | 2-Propoxypropane |
| 3. | 1-Propoxyethane | 4. | 2-Ethoxypropane |
4-Methoxytoluene will be the major product in :
1. Friedel-Crafts reaction-alkylation of anisole
2. Nitration of anisole
3. Bromination of anisole in ethanoic acid medium
4. Friedel-Craft’s acetylation of anisole
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. |
