The prouduct (P) of below reactin sequence is
`CH_(3)CH_(2) CHO overset((i) NaOH) underset((ii) Delta H ^(o+))toP`
`(iii) H_(2) // Ni , 573K`

Options

A. `CH_(3) CH_(2) CH= overset(CH_(3)) overset(|) C- CH_(3)`
B. `CH_(3) CH_(2) CH_(2) overset(CH_(3)) overset(|) CH- CH_(2)OH`
C. `CH_(3) CH_(2) CH = overset(CH_(3) )overset(|) (C) - CHO`
D. `CH_(3) CH_(2) CH= overset(CH_(3))overset(|) C - CO _(2)H`

Answer

B

Explanation

Given,
`Ch _(3) CH _(2) CHO overset((i ) NaOH ) underset((ii) Delta , H ^(o+))toP`
`(iii) H _(2) //Ni, 573K`
`CH _(3) CH_(2) - underset(O ) underset(||) C - H +CH _(3) - CH _(2) - underset(O ) underset(||) (C) -H overset(NaOH) to CH _(3) - CH _(2) -underset(OH) underset(|) (CH)- overset(CH _(3)) overset(|) (CH ) - CHO`
`Delta H ^(+)` (Dehydration)
`CH _(3) - CH _(2) - CH = underset(CH _(3)) underset(|) C - CHO underset("Reduction ") overset(H_(2) //Ni ) to CH _(3) -CH _(2) - CH _(2) -underset(CH _(3)) underset(|) (CH ) - CH_(2) - OH`
`therefore p = CH _(3) CH_(2) CH _(2) overset(CH _(3)) overset(|) (CH) - CH _(2) OH`
