Answer 2

Given: molecular formula C4H10O

A on treatment with phosphorus pentachloride gives alkyl chloride. Alkyl chloride on treatment with Mg in presence of dry ether gives a highly reactive compound B . Compound B reacts with water to give hydrocarbon C .Alkyl chloride on treatment with Na in dry ether as a solvent gives alkane 2 2 3 3 -tetra methyl butane.

To find: identify ' A ' ' B ' ' C '​

Step by step explanation: The given compounds are

A = 2,2 dimethyl ethan-1-ol

B = Grignard reagent $CH_{3}C(CH_{3})_{2}MgCl$

C = 2 methyl propane

An organic compound A with molecular formula $C_{4}H_{10}O$ on treatment with phosphorus pentachloride gives alkyl chloride.

$(CH_{3})_{3}COH + PCl_{5} --> (CH_{3})_{3}CCl + POCl_{3} + HCl$

Alkyl chloride on treatment with Na in dry ether as a solvent gives alkane 2,2,3,3 -tetra methyl butane.

$(CH_{3})_{3}CCl + 2Na + ether --> CH_{3}-C(CH_{3})_{2}-C(CH_{3})_{2}-CH_{3} + 2NaCl$

Alkyl chloride on treatment with Mg in presence of dry ether gives a highly reactive compound B .

$(CH_{3})_{3}CCl + Mg + ether --> (CH_{3})_{3}CMgCl$

Compound B reacts with water to give hydrocarbon C .

$(CH_{3})_{3}CMgCl + H_{2}O --> CH_{3}CH(CH_{3})CH_{3}$
