Which one of the following formular does not represents an organic compound?

A

`C_4H_(10)O_4`

B

`C_4H_8O_4`

C

`C_4H_7ClO_4`

D

`C_4H_9O_4`

Text Solution

Verified by Experts

The correct Answer is:

D

Work out the DBE's for each of the formulas, A fractional value of DBE indicates that the molecualr formula is an impossible one, leading to no stable structures: `DBE=C+1-(H)/(2)-(X)/(2)+(N)/(2)`
`DBE(C_4H_(10)O_4):4+1-(10)/(2)=0`
`DBE(C_4H_8O_4):4+1-(8)/(2)=1`
`DBE(C_4H_7ClO_4):4+1-(7)/(2)-(1)/(2)=1`
`DBE(C_4H_9O_4):4+1-(9)/(2)=0.5`
