Question

What is the H-C-H bond angle predicted by Lewis for CH3+?

Answer 1

bond angle = 120 °

Step-by-step explanation:

Lewis structure is used to represent the arrangement of the electrons around the atom in a molecule. The electrons are shown by dots and the bonding electrons are shown by line between the two atoms.

For
`CH_(3)^+`,

The number of valence electrons =
`(4* 1)+(1* 3)-1` = 6

The skeleton structure of the compound is in which one C molecule act as a central atom and is bonded to the three H with one sigma bond each.

Number of valence electrons used in skeletal structure = 6

So,

Remaining valence electrons = 0

The Lewis structure of the compound is shown below:

The geometry is trigonal planar which has an angle of 120 °.
