NaNH2 is too strong a base to do a dehydrohalogenation of a geminal dihalide. True or false?
False. NaNH2 is a strong base that can perform a dehydrohalogenation of a geminal dihalide.
True. NaNH2 is a strong base, but it is not suitable for dehydrohalogenation of a geminal dihalide. Geminal dihalides are compounds with halogen atoms on the same carbon atom. NaNH2 is a very strong base and would typically lead to elimination of both halogens simultaneously, resulting in the formation of an alkene. To perform a dehydrohalogenation of a geminal dihalide, milder bases like potassium tert-butoxide (KOt-Bu) or strong heating conditions may be used.
True.
NaNH2 is a strong base and can deprotonate hydrogen atoms readily. However, it is not suitable for dehydrohalogenation of geminal dihalides because it is too strong and may result in an elimination reaction instead of removing just one halogen atom. In dehydrohalogenation, the goal is to remove only one halogen atom to form an alkene. Using a milder base like KOH or NaOH would be more appropriate for this reaction.
