HYDRATION OF INTERNAL ALKYNES. GROUP 10 : FATTHEIN, SYAFIQAH, IRFAN. 

Scene 1

INTERNAL ALKYNES. no hydrogen. T here are no hydrogen bonded to triple carbon bond. 

Scene 2

T here are no hydrogen bonded to triple carbon bond

C arbon2 triple bond is not at the end of the carbon chain.

Because its connected to more than one carbon secondary, the pi bond are more stabilized by the surrounding carbon.

Enol is unstable compound, it immediately undergoes rearreangement to give more stable carbonyl compound, aldehyde or ketone.. 

Scene 3

Enol is unstable compound, it immediately undergoes  rearreangement  to give more stable carbonyl compound, aldehyde or ketone.

Enol always undergoes tautomeriation rapidly because of the high stability of carbonyl compound.. 

Scene 4

Enol always undergoes  tautomeriation  rapidly  because of the high stability of carbonyl compound.

Possible product. Alkynes produce ketones as a product.. 

Scene 5

I nternal alkynes. U nsymmetrical internal alkynes.
