Question

how will you convert propyne to 2-2 dibromopropane​

Answer 1

Answer:

React propyne with hbr it will form 2-bromopropene then it will react with hbr and gives you 2,2-di bromopropane

Answer 2

Conversion of propyne to 2-2 dibromopropane​ takes place according to the Markownikoff rule.

Explanation:

• When propyne is treated with HBr, it undergoes the Markownikoff rule by adding across triple bonds to form 2,2 - dibromopropane.
• The reaction takes place as follows -
• $CH3-C=CH + HBr --- CH3CBr=CH2 ----- CH3-BrCBr-CH3$
• When 2 moles of HBr add to 1 mole of propyne reacts together 2,2-dibromopropane is obtained. Here in this Br (bromine) is added to the C (carbon) atom having the least number of H atoms.
