There are two kinds of hydrogen atoms in adamantane molecule, one is methylene hydrogen () and the other is methylene hydrogen (-CH 2-), so there are two kinds of monochloro compounds. There are two kinds of hydrogen atoms in adamantane molecule, one is methylene hydrogen () and the other is methylene hydrogen (-CH 2-), as shown in the figure, so there are three kinds of dichlorides in this substance: on carbon 1 and 2, on carbon 1 and 3, and on carbon 1 and 4, all on carbon 2. So, the answer is: 2; 6; (2) Dioxin has eight H atoms, in which 1 h atom is replaced by 1 chlorine atom, forming a monochloroform of dioxin, and heptachlor form can be regarded as eight chlorine atoms in dioxin, in which 1 chlorine atom is replaced by 1 hydrogen atom, which are equivalent. Dichloroform has two isomers, and heptachloroform can be obtained. There are two kinds of hydrogen atoms in dioxins: there are also two kinds of monochlorides, so when the dichloride of this substance is on carbon 1, the other chlorine atom * * * has seven positions: on carbon 1, carbon 2, carbon 1, carbon 3, carbon 1, carbon 4 and carbon 60. When a chlorine atom is on No.2 carbon, the other chlorine atom has three positions: on No.2 and No.3 carbon, on No.2 and No.6 carbon, and on No.2 and No.7 carbon. At this time there are three kinds of dichlorides; Total *** 10 species; So, the answer is: two; 10.
