Question : 75 of 77

Marks: +1, -0

Solution:

The reaction sequence for formation of product I is

\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C}\equiv\mathrm{C}-\mathrm{CH}_2\mathrm{CHO}

\xrightarrow[]{\mathrm{NaBH}_4}

\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C}\equiv\mathrm{C}-\mathrm{CH}_2\mathrm{CH}_2\mathrm{OH}

\xrightarrow[]{\mathrm{PBr}_3}

\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C}\equiv\mathrm{C}-\mathrm{CH}_2\mathrm{CH}_2\mathrm{Br}

- I
