• According to the question,we have to Convert ethyne to hex-2-yne , ethyne to hept-2-yne​

•And now when ethyne reacts with NaNH2 & NH3, -C≡C- formed, when -C≡C- reacts with excess amount of C2H5Br(2 moles) ,Hex - 2-yne formed.

•And when ethyne reacts with NaNH2 & NH3, -C≡C- formed, when -C≡C- reacts with excess amount of C2H5Br and CH3Br ,Hept - 2-yne formed.

To convert

Explaination:  

To convert the following compounds,we need to follow the steps,

(a) ethyne to hex-2-yne

H-C ≡C-H + Na NH2 +CH3 Br   -----------------> HC≡C-CH3

ethyne

H C ≡C-CH3 + Na NH2 +CH3 CH2 CH2 Br  --------------->    CH3 -CH2-CH2-C≡C-CH3    

                                                                                                            hex-2-yne

(b) ethyne to hept-2-yne

HC ≡C-H + Na NH2 +CH3 Br       --------------->       HC≡C-CH3

ethyne

H C ≡C-CH3 + Na NH2 +CH3 CH2 CH2CH2 Br --------------->CH3 -CH2-CH2-CH2-C≡C-CH3

                                                                                                          hept-2-yne
