Answer:
The IUPAC name of the given compounds are
CH₃CH(OH)CH₂CHO - 3-Hydroxybutanal.
CH₃CH(Cl)CH(OH)CH(CH₃)COOH - 4-Chloro-3-hydroxy-2-methylpentanoic acid
Explanation:
- CH₃CH(OH)CH₂CHO
The parent chain contains 4 C, the word root will be 'But'. Since all C are single-bonded, the parent chain will be an alkane named butane. The compound has two functional groups, -OH group and -CHO group. -CHO group has a higher priority, So 'al' is added as a suffix by removing 'e' of the name of alkane. -OH group is substituted at the C-3 position, '3-Hydroxy' is added as a prefix.
The IUPAC name of the compound is 3-Hydroxybutanal.
- CH₃CH(Cl)CH(OH)CH(CH₃)COOH
The parent chain contains 5 C, the word root will be 'Pent'. Since all C are single-bonded, the parent chain will be an alkane named pentane. -COOH group has a higher priority, the numbering will be started from that C. The name will end with 'oic acid' by removing 'e' of the name of alkane. The other substituents are -CH₃ group (methyl) at the C-2 position, -OH group (hydroxy) at the C-3 position, -Cl group (Chloro) at the C-4 position,
Hence, The IUPAC name of the compound is 4-Chloro-3-hydroxy-2-methylpentanoic acid
