The synthesis of 3-octyne is achieved by adding a bromoalkane into a mixture of sodium amide and an alklyne. The bromo alkane and alkyne respectively are:

A

`BrCH_(2)CH_(2)CH_(2)CH_(2)CH_(2)CH_(3)` and `CH_(3)C-=CH`

B

`BrCH_(2)CH_(2)CH_(2)CH_(3)` and `CH_(3)CH_(2)CH_(2)C-=CH`

C

`BrCH_(2)CH_(2)CH_(2)CH_(2)CH_(2)CH_(3)` and `CH_(3)C-=CH`

D

`BrCH_(2)CH_(2)CH_(2)CH_(2)CH_(3)` and `CH_(3)CH_(2)C-=CH`

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3)CH_(2)C -= CH overset(NaNH_(2))to CH_(3)CH_(2)C -=CNa^(+)`
`CH_(3)CH_(2)CH_(2)CH_(2)Br+ Na^(+)C -=C CH_(2)CH_(3) to underset("Oct-3-yne")(CH_(3)CH_(2)CH_(2)CH_(2) -= C- CH_(2)CH_(3))`

Alkenes and alkynes are unsaturated hydrocarbons and undergo electrophilic addition reactions. In alkenes, the addition occurs in one step while in alkynes the addition occurs in two steps. Alkenes show geometrical isomerism but alkynes do not. Alkynes are more acidic than alkenes which are more acidic than alkanes. Both alkenes and alkynes can be prepared by the electrolysis of sodium or potassium salts of carboxylic acids. Write the major product of the reaction : (CH_(3))_(3)C-CH=CH_(2)overset(HBr)to
