Question

What are all the step down reactions in organic chemistry?

Answer 1

Stepdown reactions in organic chemistry represents the reaction in which the number of carbon atom is one less than the starting reactant. For ex., conversion of ethylchloride to methyl chloride
$$\begin{gathered} C_2{H}_{5}Cl\stackrel{O{H}^{-}}{\to }{C}_2{H}_{5}OH\stackrel{\left(O\right)/K_{2}C{r}_2{O}_7}{\to }C{H}_{3}COOH\underset{∆}{\overset{N{H}_3}{\to }}C{H}_{3}COON{H}_4 \\ \stackrel{B{r}_2/NaOH}{\to }C{H}_{3}N{H}_2\stackrel{HN{O}_2}{\to }C{H}_{3}OH\stackrel{SOC{l}_2}{\to }C{H}_{3}Cl \end{gathered}$$
Like this any higher homologous is converted to its lower member is called stepdown reaction
