Question

In the IUPAC naming system, an aldehyde is named by replacing the e of the name of

the corresponding alkane with
A.al
B.yne
C.one
D.ene
E.ol

Answer 1

In the IUPAC system, an aldehyde is named by replacing the 'e' of the corresponding alkane name with 'al', resulting in names like methanal for formaldehyde and ethanal for acetaldehyde. The correct answer is option A.

Step-by-step explanation:

In the IUPAC naming system, an aldehyde is named by replacing the e of the name of the corresponding alkane with al. For example, the aldehyde derived from ethane is named by dropping the e from ethane and adding al, resulting in the name ethanal. Methanal and ethanal are the IUPAC names for formaldehyde and acetaldehyde, respectively. This rule applies similarly to other alkanes when named as aldehydes in the IUPAC system.
