Answer» Solution :`CH_3 CH_2 OH + HBR overset(Delta)to CH_3CH_2 Br + H_2 O ` `CH_3 CH_2 underset(CH_3)underset(|)CH- underset(CH_3)underset(|)CH-OH + Na to CH_3 CH_2 - underset(CH_3)underset(|)CH-underset(CH_3)underset(|)CH-O^(-) Na^+ + H_2 ` `CH_3 CH_2 underset(CH_3)underset(|)CH-underset(CH_3)underset(|)OH - O^(-) Na^+ + CH_3 CH_2 Br overset(S_N^2)to underset("2-Ethoxy-3-methylpentane")(CH_3CH_2-underset(CH_3)underset(|)CH-underset(CH_3)underset(|)CH-OCH_2 CH_2 + NABR)` |
