The IUPAC name of the following comopound is :
  1. (A)n-propyl-2-bromo-5-methylheptanoate✓ Correct
  2. (B)2-bromo-5-methylhexylpropanoate
  3. (C)2-bromo-5-methylpropanoate
  4. (D)n-propyl-1-bromo-4-methylhexanoate

Answer: (A)

Solution

The carbonyl carbon of the acid part is C-1, and the longest chain through it runs for seven carbons, making the acid a heptanoate, with a bromine on C-2 adjacent to the carbonyl and a methyl branch on C-5. The group attached to the ester oxygen is an unbranched three-carbon chain, that is -propyl. The ester is therefore -propyl 2-bromo-5-methylheptanoate.
