Question

Give the condensed formula of hexanedial:
(A) \[OHC{\left( {C{H_2}} \right)_4}CHO\]
(B) \[OHC{\left( {C{H_2}} \right)_3}CHO\]
(C) \[OHC{\left( {C{H_2}} \right)_4}COOH\]
(D) \[COOH{\left( {C{H_2}} \right)_3}COOH\]

Answer 1

Hint:Here firstly try to find out the number of carbons matching the above stated name and try to find out from the name of the functional group attached this will further help to find the condensed formula more easily.

Complete answer:Here we need to find the condensed formula of the hexanedial so we need to know that the condensed formula is the one which is squeezed into a short . further we are talking about the hexanedial where hexane means the six carbon containing compound and moreover the dial says that that there are two aldehyde groups attached to the six carbon containing compound. Further we will discuss here more on the aldehydes and that too the hexanedial. So as we know that the aldehydes are obtained when we found a CHO as a functional group. We should further know that the volatile aldehydes have the pungent smell.

Hence the option (B) is correct.

Note:Condensed structural formulas are also helpful when showing that a group of atoms is connected to a single atom in a compound.we concluded from here that the prefixes with the functional group further helps to find the number of functiona;l groups attached.
