Answer 2

Answer

• The correct option is c) $sp_3\:and\:sp_3$

• Hence, the molecule has tetrahedral geometry at both the carbon sites.

Explanation

See the attachment for the structure for $C_2H_5Cl$ ,we observe that :-

• Both the carbon has 4 sigma bonds.

• They are joined in a tetrahedral fashion.

Concept to remember

In organic compound involving carbon atom, we can find its hybridization easily.The process is :-

• If the carbon atom forms 4 sigma bonds, hybridization is $sp_3$

• If the carbon atom forms 3 sigma bonds, hybridization is $sp_2$

• If the carbon atom forms 2 sigma bonds, hybridization is $sp$

Examples

Therefore,

• The carbon atom is $sp_2$ hybridized in ethene while it is sp in ethyne.
