Answer:

It's Butanoic acid

CH3-CH2-CH2-COOH

Explanation:

-CH3 has the 0.95 triplet band

-CH2 has the 1.65 multiplet band having five proton around it

-CH2 has the 2.30 triplet band because it is attached to the carbon bearing the carboxylic group

While the last singlet H at 11.8 is that of the -COOH.
