C2H2NaNH2−−−−ExcessCCC2H5Br−−−−ExcessC2H5CCC2H5HBr−−−ExcessCH3CH2CBr2CH2CH2CH3

Excess of soda amide abstracts 2 acidic H atoms from acetylene.
This is followed by reaction with 2 moles of ethyl bromide to form 3-hexyne.
In the final step, 2 moles of HBr are added to form 3,3-dibromohexane.
Hence, the given statement is true and the correct answer is 1.
