An compound (A) which undergo halogorm reaction give compound (B) on reduction . Compound (B) on dehydration with conc. `H_(2)SO_(4)` gives compound ( C ) which forms secondary butylbromide with HBr. Identify (A).

A

`CH_(3)OCOCH_(2)CH_(3)`

B

`CH_(3)CH_(2)CH_(2)CH_(2)CHO`

C

`CH_(3)CH_(2)CH_(2)CH_(2)OH`

D

`CH_(3)CHOHCH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`C+ HBrrarr CH_(3)-CH_(2)-underset(Br)underset(|)(C)H-CH_(3)`
`:. C :` But-2-ene`//` But -1-ene
A give haloform test. Therefore A contains `CH_(3)-overset(O)overset(||)(C )-` group.
`A overset([H])(rarr)B `
`B overset("dehydration")(rarr)C :.B :` Butan -2-ol `//` Butan-1-ol
`:. A : ` Butanal`//` Butan -2-one
But A contains `CH_(3)-overset(O)overset(||)(C) - ` group.
`:. A : CH_(3)COCH_(2)CH_(3)`
