• B. propan-1-al
• C. propan-3-one
• D. propan-1-ol

Answer 1

Answer: (A), (D)

propan-1-ol

• There are three carbon atoms present in the parent chain of the compound and hence, the word root is 'prop'.
• Since the -OH group is attached to the terminal carbon atom, the numbering will start from that particular carbon atom.
• For alcohols, the prefix used is '-ol'.
• Hence, the IUPAC name of the compound is propan-1-ol.
