Solution
The correct option is DCH3−(CH2)3−O−CH2CH3 In the given sequence, the compound Z is CH3−(CH2)3−O−CH2CH3. HBr in presence of peroxide gives anti Markovnikoff addition product. A molecule of HBr is added across C=C double bond. Br is added to C atom having more number of H atoms. 1o alkyl halide on reaction with C2H5ONa gives SN2 reaction. Bromide ion is replaced with ethoxide ion.
