Question

HOW MANY 109°28' ANGLES ARE THERE IN CH4??

Answer 1

Answer:

4 bond angles in methane

Answer 2

The $CH_{4}$ molecule in total contains six 109°$28^{'}$ bond angles.

• In $CH_{4}$, the four hydrogen atoms are arranged at the corners of regular tetrahedrons forming a tetrahedral structure.
• In a tetrahedral molecular geometry, a central atom is placed at the centre with four substituents that are located at the corners of a tetrahedron.
• Sine all the bonds in $CH_{4}$ are equivalent, the bond angle is 109°$28^{'}$.

• Also, there are no lone pairs on the central carbon atom present in the $CH_{4}$ molecule.
