Reaction One
Ketone ---> dichloroalkane(geminal) ------> chloroalkene ------> alkyne

Reaction 2 is  double dehydrohalogenation to convert vicinal dihalide to alkyne

Reaction three - First convert vicinal dihalide to alkyne by double dehydrohalogenation using two moles of NaNH2 ---->Deprotonation (Removal of acidic H  from sp carbon) -------> SN2 Nucleophilic substitution reactions CH3CH2I

Now you can add them to get total moles
