An organic compound A(C_4 H_7 C_(13)) yields (B) when treated with aq. KOH. (B) upon treatment with C_2 H_5 OH in presence of acid gave (C) which upon reducing with LiAIH_4 gave (D) and (E). (B) upon treatment with NH_3 followed by heating with P_4 O_(10) and subsequent hydrolysis gives back (B). Sodium salt of (B) on Kolbe's electrolysis gave 2, 3-dimethylbutane at anode. Compound (D) and (E) respectively are

Answer»

`CH_3 CH_2 CH_2 OH, C_2 H_5 OH`
`CH_3 - UNDERSET(CH_3)underset(|)CHCH_2 OH, C_2 H_5 OH`
`CH_3CH_2 CH_2 CH_2 OH,C_2 H_5 OH`
`CH_3-underset(CH_3)underset(|)CHCH_2 - OCH_3- CH_3OH`

Solution :`underset((C))(CH_3-overset(CH_3)overset(|)CH-COOC_2 H_5) overset(LiAlH_2)to underset((D))(CH_3-overset(CH_3)overset(|)CH-CH_2)underset((E))(OH+C_2 H_5OH)`
