Write the structure of the major organic product in each of the following reactions :
`(a) (CH_(3))_(3)CBr + H_(2)O overset("heat") to `
`(b) (CH_(3))_(2)CH - CH(Br)CH_(2)CH_(3) underset("ethanol /heat") overset(C_(2)H_(5)ONa) to `
`(c) CH_(3)CH_(2)Cl + SbF_(3) overset("heat") to `
`(d) CH_(2) = CHCH_(2)Br + CH_(3)C -= CNa overset("liq."NH_(3))to `

Explanation

`(a) underset("Butyl bromide") ((CH_(3))_(3)CBr) + H_(2)O overset("heat") to underset("tert. butyl alcohol") ((CH_(3))_(3)C - OH + HBr) `
`(b) CH_(3) - underset(CH_(3))underset(|)(CH) - overset(Br) overset(|)(CH) - CH_(2) - CH_(3) underset("ethanol/heat") overset(C_(2)H_(5)ONa) to underset(("Saytzef Rule"))underset("More branched alkene ")(CH_(3) - underset(CH_(3))underset(|)C = CH - CH_(2) - CH_(3)) + NaBr + C_(2)H_(5)OH `
`(c) 3CH_(3)CH_(2)Cl + SbF_(3) overset("heat") to 3CH_(3)CH_(2)F + SbCl_(3) `
`(d) CH_(2) = CH - CH_(2)Br + CH_(3)C -= CNa overset("liq."NH_(3)) to CH_(2) = CH - CH_(2) - C -= C - CH_(3) + NBaBr `
