Question

You are given an organic compound having the molecular formula C₃H₈. Give the name and formula of the compound formed :

(a) when one H atom of C₃H₈is replaced by a Cl atom.
(b) when one H atom of C₃H₈is replaced by OH group.
(c) when one H atom of C₃H₈is replaced by a CHO group.
(d) when one H atom of C₃H₈is replaced by a COOH group.
(e) when two H atoms jointed to the middle carbon atom of C₃H₈are replaced by one O atom.

Answer 1

The compound formed when one H atom of C₃H₈ is replaced by Cl, OH, CHO, COOH or an O atom are named 1-chloropropane, 1-propanol, propionaldehyde, propanoic acid, and propylene oxide, respectively.

Step-by-step explanation:

(a) When one H atom of C₃H₈ is replaced by a Cl atom, the compound formed is called 1-chloropropane. The molecular formula of 1-chloropropane is C₃H₇Cl.

(b) When one H atom of C₃H₈ is replaced by an OH group, the compound formed is called 1-propanol. The molecular formula of 1-propanol is C₃H₈O.

(c) When one H atom of C₃H₈ is replaced by a CHO group, the compound formed is called propionaldehyde. The molecular formula of propionaldehyde is C₃H₆O.

(d) When one H atom of C₃H₈ is replaced by a COOH group, the compound formed is called propanoic acid. The molecular formula of propanoic acid is C₃H₆O₂.

(e) When two H atoms jointed to the middle carbon atom of C₃H₈ are replaced by one O atom, the compound formed is called propylene oxide. The molecular formula of propylene oxide is C₃H₆O.
