(A) `A(C_(7)H_(14)) overset(O_(3)//Red)(rarr)B(C_(3)H_(6)O)+C`
(B) Gives positive Tollens test but negative iodform test.
(C ) Give negative Tollens test but positive iodoform test.
The compound (A) is:

A

a.

B

b.

C

c.

D

d.Both `(a)` and `(b)`

Text Solution

Verified by Experts

The correct Answer is:
D

`DU` in `A=((2n_(C)+2)-n_(H))/2=((2xx7+2)-14)/2=1^(@)`
1 DU in (A) means it contains one `(C=C)` bond.
(B) is an aldehyde with three `C` atoms, since it gives positive Tollens test.
Therefore, the structure of (B) is `MeCH_(2)CHO`.
(C ) is a ketone with four `C` atoms since the total number of `C` atoms in (A) is seven and it should be `MeCOCH_(2)CH_(3)`. (It gives positive iodoform test.)
Therefore, structure of (A):

(A) can show two isomers, cis and trans.
