Select the correct option based on statements below:
| Assertion (A): | The IUPAC name of the compound is 2-ethoxy-2-methylethane. |
| Reason (R): | In IUPAC nomenclature, ether is regarded as a hydrocarbon derivative in which a hydrogen atom is replaced by —OR or -OAr group [where, R = alkyl group and Ar = aryl group]. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

Select the correct option based on the statements below:
| Assertion (A): | The bond angle in ethers is slightly less than the angle of tetrahedral. |
| Reason (R): | There is repulsion between the two bulky (— R) groups. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
