Chemistry >> Organic Chemistry >> Alkyl Halides, Alcohols and ethers IIT JEE

Primary alkyl halide C4H9Br (a) reacted with alcoholic KOH to give compound (b).Compound (b) is reacted with HBr to give (c) which is an isomer of (a). When (a) is reacted with sodium metal it gives compound (d), C8H18 which is different from the compound formed when n-butyl bromide is reacted with sodium. Give the structural formula of (a) and write the equations for all the reactions.

Joshi sir comment

Considering the electrode potential of hydrogen to be zero, electrode potential of fluorine is +2.87 volt. It implies that fluorine is best oxidising agent, and thus it oxidises oxygen in the given reaction. Besides it low bond energy of fluorine is also a factor for its dissociation and participation in the reaction.

Joshi sir comment

Amount of DCl = 4 milimole

Amount of NaOD = 8 milimole

After reaction of acid and base

Amount of NaOD remaining = 4 milimole

Total volume = 100 ml = 0.1 lit

$s o [O D] = 4 * 10^{- 3} / 0.1 = 4 * 10^{- 2} (1) G i v e n p D = 13.6 s o \log [D^{+}] = - 13.6 = \bar{14} . 4 \Rightarrow [D^{+}] = 2.5 * 10^{- 14} (2) N o w s o l v e$
