Question

propanal, is a 3- carbon compound with the
- functional group.
a) carboxylic acid b. Aldehyde. C) ketone
I d) Alcohol.​

Answer 1

Answer:

Option b. Aldehyde

The functional group of propanal is Aldehyde.

Answer 2

Propanal is 3-carbon compound with the functional group aldehyde (option b).

• Aldehyde (Propanal) is a carbon compound in which carbon atoms form four covalent bonds in the following way:

        R-CH=O

1. 1st covalent bond is a single covalent between carbon (C) and alkyl group (R). Where R = C₂H₅-
2. 2nd covalent bond is a single covalent between carbon (C) and hydrogen (H).
3. 3rd covalent bond is double covalent and between carbon (C) and oxygen (O).

• From the IUPAC nomenclature system suffix, "al" denotes the aldehyde group.
• The suffix "one" represents the ketone functional group.
• The suffix "ol" represents the alcohol functional group.
• The suffix "oic acid" signifies the carboxylic acid functional group.
• Hence, Propanal is a 3-carbon compound with an aldehyde functional group.
