1.

Arrange the given set of compounds in order of increasing boiling points. I. 1-chloropropane II. Isopropyl chloride III. 1-chlorobutane

Answer»

`II lt III lt I`
`I lt II lt III`
`II lt I lt III`
`III lt I lt II`

SOLUTION :For n-alkyl HALIDES, the b.p. increases as the size of the alkyl chain increases, i.e., the b.p. of 1-chlorobutane (III) is higher than that of 1-chloropropane (I).
THUS, OPTION (c), i.e., IIltIltIII is correct.
