Question

When two halogen atoms are attached to same carbon atom
then it is :
(a) vic-dihalide (b) gem-dihalide
(c) α, ⍵ -halide (d) α, β -halide

Answer 1

When two halogen atoms are attached to same carbon atom then it is called as geminal -dihalide .

1) The common name of these types of molecules is Alkylidene Halide where the name of alkyl depends on number of carbon atoms and name of halide depends on the halide atom attached.

2) Example: name of Ch3-Ch3Cl2 is

Ethylidene Chloride.

3) So option (b) is the right answer.

Answer 2

When two halogen atoms are attached to same carbon atom  then it is gem-dihalide.

Explanation:

Halides

• These are binary compounds in which one part is element and another is halogen atom. Its electronegativity is less compared to halogens.
• Using silver nitrate solution several halides are tested.

Geminal dihalides

• Alkylidene dihalides or alkylene dihalides are identical halogen atoms which has dihaloalkanes.
• Halogen atoms are placed in the similar carbon atom are germinal dihalides.
• Germinal is connected between two functional group and atoms which attaches the similar atom.
• It is important in the concept of spectroscopy and synthesis.
