Concept approach-
- This is example of williamson ether synthesis.
- Williamson ether synthesis involve reaction of SN2 reaction between alkoxide ion and a halide ion to give ether.
- Alkoxide ion act as a nucleophile and halide ion act as a electrophile.
Solution-
- Only option A and C have alkoxide ion and alkyl halide reagent so B and D are ruled out.
- Amongst option A and C, stable alkoxide ion will be best suitable for Williamson synthesis of ether.
- Option A have alkoxide formed from secondary alcohol.
- Option C have alkoxide formed from primary alcohol.
- Due to +I effect of electron donating methyl groups alkoxide ion in A is more stabilized than B.
- Therefore it act best as nuceophile.
Therefore, option A is correct.
