The reaction may undergoes if we have use bulky alkoxide(sodium tert-butoxide) and primary halide(chloroethane) as shown process I or we have use bulky alkyl halide(tert-butyl chloride) and primary alkoxide(sodium) ethoxide as ahown in process II. Among these two peocesses, Process I is more favourable because this reaction undergoes through SN1 pathway so reacting alkyl halide should be less hindered in order to be attacked by O- from alkoxide. So the primary alkyl halide is more favourable for this reaction.
