Bromomethane to Propanone is a multistep conversion.

1.  Conversion of bromomethane to methylnitrile:  

\mathrm{CH}_{3}-\mathrm{Br}+\mathrm{KCN} \rightarrow \mathrm{CH}_{3} \mathrm{CN}+\mathrm{KBr}

2.  Conversion of methylnitrile to acetic acid:

\mathrm{CH}_{3}-\mathrm{CN}+\mathrm{H} 2 \mathrm{O} \rightarrow \mathrm{CH}_{3}-\mathrm{COOH}

3.  Formation of calcium salt of acetic acid:

2 \mathrm{CH}_{3}-\mathrm{COOH}+\mathrm{Ca}(\mathrm{OH})_{2} \rightarrow\left(\mathrm{CH}_{3} \mathrm{COO}\right)_{2} \mathrm{Ca}+2 \mathrm{H}_{2} \mathrm{O}

4.  Conversion of calcium acetate to acetone by dry distillation for forms acetone as final product:  

\left(\mathrm{CH}_{3} \mathrm{COO}\right)_{2} \mathrm{Ca}+\text { Heating } \rightarrow \mathrm{CH}_{3}-\mathrm{CO}-\mathrm{CH}_{3}+\mathrm{CaCO}_{3}

This is the conversion of Bromomethane to propanone.
