(a) Write the product for the following reaction:

$2{\mathrm{CHCl}}_3+{\mathrm{O}}_2\to \mathrm{A}+\mathrm{B}$

(b) Arrange following in increasing order of boiling points.

1-iodobutane, 1-bromobutane, 1-chlorobutane, Butane

OR

Name the reagents used to convert

(a) Bromoethane to butane

(b) 1-Chloropropane to 1-nitropropane

(a) The products A and B in the given reaction are COCl₂ and HCl.

(b)More the molar mass  of compound, more will be boiling point. So boiling point order will be Butane<1−chlorobutane<1−bromobutane<1−iodobutane.

As molecular mass is increasing so boiling point also increase.

OR

(a)  Na/ether

(b) ${\mathrm{AgNO}}_2$
