Chapter 7: Q 29P (page 314)

Give the major product obtained from the reaction of each of the following with excess HCI:

a.CH3CH2C≡CH

b.CH3CH2C≡CCH2CH3

c.CH3CH2C≡CCH2CH2CH3

Short Answer

Expert verified

a)

b)

c)

Step by step solution

01

How will reaction proceed

Excess HCl is used which do markoniv addition and replaces triple bond to single bond by chlorine.

In unsymmetrical alkynes two products will form as Cl can attached with any triple bonded carbon atom but not with terminal carbon atom.

02

Final answer

a) Excess HCl is used which do markoniv addition and replaces triple bond to single bond by chlorine.

b) In symmetrical alkyne in excess HCl Cl can attach with any carbon atom as product will be same.

c) In unsymmetrical alkynes two products will form as Cl can attached with any triple bonded carbon atom but not with terminal carbon atom.
