The missing structures `A` and `B` in the recation sequence:
`R -CH_(2)-CH_(2)OH overset(AI(2)O_(3))underset(350^(@)C)rarrR-CH=CH_(2)overset((i)O_(3))underset((ii)Zn//H_(3)O)rarr`
`RCHO +A, RCHO overset(Reduct)rarrB`, are

A

`CH_(3)OH,RCOOH`

B

Methanal, `RCH_(2)OH`

C

Ethanal, `RCOOH`

D

Methanal, `RCHOHR`

Text Solution

Verified by Experts

The correct Answer is:
B
`R-CH_(2)CH_(2)OHoverset(A1_(2)O_(3))underset(350^(@)C)rarrR-CH=CH_(2)overset((i)O_(3))underset((ii)Zn,H_(3)O^(o+))rarr`
`R-Cho +CH_(2)O (A)`
`R-CHO overset("Methanol Reduce")rarr R-underset((B))(CH_(2)OH)`
